The identification means of work pieces utilized for its identification and traceability throughout the manufacturing process and product life cycle has become a necessity for the high productivity required by the increasingly competitive global manufacturing operations having multiple part variants within a products' family, using multiple work-piece part work holding fixtures, and at multiple manufacturing locations, being produced via sequential machining-manufacturing operations, and manufacturing processes. As the work-piece part's identification data is frequently required by the Manufacturer's Quality Plan, Industrial Standards Organizations, Regulatory Agencies, customer(s) specifications, etc., such as for patient specific replacement(s), the work-piece part's design revisions, the product's assembly of multiple work-piece parts having a combined tolerance stack-up, a work-piece part's/Article's certificate of origin, Department of Defense components, product recall campaigns, forensic identification, etc.
Manual work-piece direct part marking may not be desirable, and or suitable, for most modern manufacturing processes. Because it is susceptible to human error(s) for correctly marking the work-piece part/article, with errors negating the intended purpose of the work-piece parts'/articles' identification, and potentially injurious to personnel, via using a hammer to impact the hardened steel character forming stamp(s) onto the work piece's surface, to a semi-controlled depth, to indent and displace the surface material of the work-piece part/article to create a readable character and or symbol causing the displaced material to project above the previously smooth surface.
Semi-automatic work-piece direct part marking can be done as a secondary operation to the primary manufacturing process that may not be desirable, and or suitable, for manufacturing processes that requires integrity of the data because it is susceptible to error(s) for correctly marking the corresponding work-piece part/article with the required data, with errors negating the intended purpose of the work-piece part's/article's identification.
Automatic point-of-manufacture work-piece part/article engraving for marking/identification minimizes the opportunities for data error(s) and eliminates the potential for injuring personnel.
Automatic point-of-manufacture Work-piece Engraving is desirable at the point of manufacturing the work-piece part/article because of its being an integral operation of the production process to ensure the product's work-piece part/article marking and identification data integrity.
Automatic Work-piece Engraving is desirable to reduce the operator's potential for injury by eliminating the use of having to manually impact the hardened character forming stamp(s) against the work-piece part/article.
Currently, there are two common methodologies for Automatic point-of-manufacture direct work-piece marking spindle tooling used within Computer Numerically Controlled (CNC) Machine Tools, both having a different single point tool for either cutting material from the work-piece surface or impacting the work-piece part/article to indent and displace the work-piece part's/article's base material to create a readable character and or symbol:
Cutting material from the work-piece surface using one rotating fluted cutting tool being plunged into the work-piece to a specific depth for the tool's cutting land(s) to remove the material from the work-piece surface while it's being moved parallel to the work-piece part's/article's surface by the motion of the CNC machine tool, to “write” the segments of a character via the removed material of the work piece's cutout profile cross section at specific location(s) and or along a path of lines and or curves on the work-piece part's surface to engrave a readable character and or symbol.
Impacting via the “dot-peen” or scribing via the “Square-Dot” methodologies onto the work-piece part to indent and displace the work-piece material using a percussion motion to plunge a single point stylus into the work-piece to a depth to displace the material of the work piece's surface with the tool being lifted from the work-piece part's/article's surface as the tool is being moved parallel to the work-piece surface by the CNC machine tool to the next specific location(s) to “write” the character via the visually contiguous/adjacent pointed stylus at a specific location(s) or along a path of lines and or curves on the work-piece part's surface making a readable character and or symbol.
Impacting the work-piece to indent and displace the work-piece material using a percussion motion to plunge multiple single point styluses into the work-piece to a depth to displace the material of the work piece's surface with the tool being lifted from the work-piece surface to “write” the next character via the visually contiguous/adjacent multiple pointed styluses impact “dots or dot-peen” at a specific location(s), or along a path of lines and or curves on the work-piece part's surface making a readable character and or symbol.
Both of the single stylus direct part marking processes described above have the same initial limitation for the Automatic point-of-manufacture work-piece direct part marking and identification operation, as that of being a time consuming operation for an expensive machine tool and manufacturing process via being constrained by their respective single point tooling for the work-piece part's surface material displacement.
The higher manufacturing costs and reduced tool life for the rotating Cutting tool method of engraving are comparable to the standard single point CNC cutting tools.
The Impacting pointed stylus direct part marking devices are more expensive and potentially damaging to the CNC machine tool's precision spindle bearings. While the smoothness of the work-piece surface is disrupted by the impacting of the pointed stylus potentially affecting its assembly to an adjacent work-piece part, while the displaced work-piece surface material can become a source of contamination in the application of the work-piece part(s) in its assembly.
The use of a “permanent” marking pens and inks to mark/identify the work-piece has multiple limitations such as:
The use of an adhesive backed printed label to mark/identify the work-piece has multiple limitations such as:
Considerations for the productive machining of work piece parts and the increased necessity for the automatic point-of-manufacture Direct Work-piece Marking and Identification:
The automatic point-of-manufacture direct work-piece part marking operation is an additional machining operation that requires its minimization to reduce the CNC machine's overall cycle time to a minimum, as the cost basis for CNC Machining is a combination of cost effective equipment utilization, the quality, and the quantity of work-piece parts/articles being produced in the shortest time possible.
However, the total manufacturing costs for the high productivity sequential machining of multiple work-piece parts will increase when the shorter cycle time of not marking the work-piece parts causes the erroneous sequential transferring of work-piece parts between the sequential machining operations and the increased difficulty for the root cause defect analysis and the corresponding corrective action required for eliminating defective and out of tolerance work pieces. The sequential machining of multiple work-piece parts, correctly via multiple operations, can be dependent upon using the same manual transfer sequence for the work-piece parts from one of the previous sequential work-piece parts' fixture location to the next sequential work-piece parts' fixture location for the next machining/manufacturing operation.

Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
The technologies disclosed encompass a selectable character Multiple Orbital Stylus Engraving Tool (MOSET), also referred to herein as Multiple Stylus Orbital Engraving Tool (MSOET). The Selectable Character Multiple Stylus Orbital Engraving Tool is a multiple stylus engraving device, with the styluses being individually selectable, and operatively coupled to an orbital motion of the machine tool causing the selected stylus(es) to engrave in either a dot or dot-matrix pattern of alpha numeric and or symbol and or machine readable characters and or code.

Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.
A selectable symbol engraving tool for use with a CNC machine is disclosed. In an embodiment, the engraving tool includes a housing and an array of styluses supported in the housing. A pattern disk is rotatably supported in the housing and is connectable to a spindle of the CNC machine. The pattern disk includes a plurality of hole patterns, each selectable via rotation of the spindle and including one or more clearance holes corresponding to a symbol. The array of styluses is positioned to confront a selected one of the plurality of hole patterns such that styluses corresponding to the clearance holes are retracted and the remaining styluses are extended. The extended styluses are operative to engrave the symbol corresponding to the selected hole pattern in a work piece via orbiting about a virtual axis of rotation when the selectable character engraving tool is moved in a circular motion by the CNC machine.
Computer Numerically Controlled (CNC) machine tools typically have three orthogonal linear axes (X, Y, & Z) for the horizontal spindle, a rotary table axis (B) for the work-piece parts' work holding fixture. The interchangeable spindle tool can be used with the Selectable Character Multiple Stylus Orbital Engraving or Multiple Orbital Stylus Engraving Tool, as shown in
With the conventional three linear axes CNC machine tool (3) having a first X axis (37), a second Y axis (38) perpendicular to the first X axis, and a third Z axis (39) perpendicular to the plane of the first X axis and second Y axis, having either a manual or automatic tool changing function. Optionally, the CNC machine tool can have a fourth axis (40) being a rotary B axis that rotates the work-piece part pallet (41) on an axis that is parallel to the Y axis with optionally having additional rotation and pivoting axes being used for machining the work-piece part as may be required.
The Selectable Character Multiple Stylus Orbital Engraving Tool (6) is placed into the machine's spindle (31) and the through the spindle pressurized air is turned on to enable the Selectable Character Multiple Stylus Orbital Engraving Tool (6).
The “M398” is a NC-Program Macro command developed by the machine tool manufacturer of the CNC machine tool (3) to turn on the pneumatic solenoid valve to direct pressurized air through a pneumatic lubricator that dispenses a metered amount of lubricating oil mist into the passing pressurized air stream into the through spindle pneumatic coupling means (61), for the Selectable Character Multiple Stylus Orbital Engraving Tool (6) via the pneumatic passage (63) where it lubricates the internal components of the tool before being discharged onto the work-piece via the operational clearance between the stylus (77) and the main housing (6).
The Selectable Character Multiple Stylus Orbital Engraving Tool's (6) multiple styluses are operatively selected via rotation of the machine's spindle (31) to a specific orientation angle that corresponds to a specific character or symbol.
The optional B axis (40) positions the work-piece surface (21) toward the machine's spindle (31).
The spindle is positioned via the X (37) and Y (38) axes to a position that corresponds with the work-piece (2) location(s) to be engraved.
The Z axis (39) places the Selectable Character Multiple Stylus Orbital Engraving Tool (6) onto the work-piece (2).
The X (37) and Y axes (38) are circularly interpolated via the CNC machine tool's helical motion command in a helical motion path that causes each of individual multiple styluses to rotate via orbiting about a virtual axis of rotation causing the individually selectable engraving stylus(es) (77-A) to drill into the work-piece part to a specific depth via the Z axis (39), while the Selectable Character Multiple Stylus Orbital Engraving Tool (6) is not rotating.
When the engraving operation is finished, the Z axis (39) retracts the Selectable Character Multiple Stylus Orbital Engraving Tool (6) from the work-piece part (2) for the process to be completed or repeat the process at another X (37) and Y (38) axes position, as or if required.
In an embodiment, the Selectable Character Multiple Stylus Orbital Engraving Tool (6), having the Uniquely Identifiable Engraved Indention Character(s)/Pattern(s) (23) being operatively selectable via the rotation of the machine's spindle (31) to a specific orientation angle, consisting of the Selectable Character Multiple Stylus Orbital Engraving Tool's (6) components as shown in
In an embodiment, the selectable symbol engraving tool can be used with a computer CNC machine as shown in

With reference to
It should be appreciated that various methods are inherent in the disclosed structures. In at least one embodiment, a method for engraving a selected symbol into a work piece with a CNC machine includes supporting an array of styluses on the spindle-nose of a CNC machine. The method can further include selecting a plurality of active styluses corresponding to the selected symbol from the array of styluses. The plurality of active styluses is extended and the spindle-nose is moved toward the work piece causing the plurality of active styluses to contact the work piece. The method further includes moving the spindle-nose in a circular motion thereby causing the plurality of active styluses to orbit about a virtual axis of rotation.
In some embodiments, the method also includes preventing rotation of the array of styluses with respect to the spindle-nose. However, it should be understood that the individual styluses are rotatable within the housing. In some embodiments, the step of selecting the plurality of active styluses comprises rotating a pattern disk with a spindle of the CNC machine. In some embodiments, the method includes urging the styluses toward the pattern disk with, for example, a pneumatic air supply. In some embodiments, the pattern disk includes a plurality of hole patterns, each selectable via rotation of the spindle and including one or more clearance holes corresponding to a symbol and wherein the array of styluses is positioned to confront a selected one of the plurality of hole patterns such that styluses corresponding to the clearance holes are retracted and the plurality of active styluses are extended and operative to engrave the selected symbol corresponding to the selected hole pattern in the work piece.
The Character pattern to be engraved is determined via the stylus pattern disk (68) as shown in
The stylus pattern disk (68) Part-68.12 is optimized for 12 characters being the numeric 0-9, the Plus sign “+”, and the Minus sign “−” having 12 corresponding character positions.
The stylus pattern disk (68) Part-68.5 is a selectable 5 bit pattern for the binary equivalent 0-31 having 32 corresponding character positions for an unlimited programmable dot- matrix pattern of alphanumeric characters and or syntax and or symbols and or machine readable characters and or 2D barcodes.
The engraving stylus is pneumatically retraced (77-B) into the adjacent stylus clearance hole of the character pattern disk of the Selectable Character Multiple Stylus Orbital Engraving Tool (6) while it is in the stationary position for engraving.

The canceling of the pneumatic stylus retraction during the rotation of the stylus pattern disk for the Selectable Character Multiple Stylus Orbital Engraving Tool (6):
The individual stylus self-alignment/orientation is via the orbital motion of the Selectable Character Multiple Stylus Orbital Engraving Tool (6) orbiting about a virtual interpolated axis.
Before engraving/marking the work-piece (2), the actuated styluses (77-A) are positioned adjacent to the work-piece at a clearance plane and are not contacting the work piece, then utilizing the initial interpolated 3 axes, or optionally 2 axes of interpolated motion having the sequential Z- motion, of motion for the self-alignment and uniform orientation of the individual actuated styluses (77-A) as they contact the work-piece part surface (21).
The tools orbital circular interpolated motion of the X and Y axes (37 and 38) as the -Z axis (39) motion cause the leading edge of the stylus (77-A) to contact the work-piece surface (21) causing the stylus to rotate.
The -Z axis (39) motion causes the styles lead edge of the stylus (77-A) to contact the work-piece surface (21) causing the individual actuated styluses (77-A) to contact the corresponding stylus bearing sphere (80.1) and compress its corresponding elastomeric compliance member (80) to apply pressure to the leading edge of the stylus (77-A) as it contacts the work-piece surface (21) with the tools orbital circular interpolated motion of the X and Y axes (37 and 38) causing the stylus to rotate.
The stylus cutting tip could be a replaceable component detail for the Selectable Character Multiple Stylus Orbital Engraving Tool (6) having the styluses (77) being either a solid piece of carbide or other appropriated work-piece part (2) cutting material or a combination of multiple components to create the stylus (77).
The Selectable Character Multiple Stylus Orbital Engraving Tool (6) could utilize self- lubricating components in its construction by having the components fabricated from base materials that are coated with a self-lubricating material and or a combination of self-lubricating base materials.
The Selectable Character Multiple Stylus Orbital Engraving Tool (6) could utilize a CNC Machine Tool Controller having a functional Personal Computer control schema to facilitate an unlimited programmable dot-matrix pattern of alphanumeric characters and or syntax and or symbols and or graphics and or machine readable characters and or 2D barcodes via the Pattern Disk Part 68.5 for selecting the 5 bit pattern for the binary equivalent 0-31.

The Selectable Character Multiple Stylus Orbital Engraving Tool could utilize the CNC Machine Tool Controller having a Separate Processing Module and or Character Selection Interface to operate the Programmable Selectable Character Multiple Stylus Orbital Engraving Tool to facilitate an unlimited programmable dot-matrix pattern of alphanumeric characters and or syntax and or symbols and or graphics and or machine readable characters and or 2D barcodes via the Pattern Disk Part 68.5 for selecting the 5 bit pattern for the binary equivalent 0-31.
Operation of the Selectable Character Multiple Stylus Orbital Engraving Tool via a CNC machine tool:
The Selectable Character Multiple Stylus Orbital Engraving Tool (6) can be implemented via the use of a keyed and orientable interchangeable spindle tool holder (32) having a selectable, through spindle, pressurized pneumatic passage (63) selectively and operatively coupled with the mating shank (60) having an internal pneumatic passage (63) or an optional external pneumatic passage means (Standard trade item not shown). With the Selectable Character Multiple Stylus Orbital Engraving Tool (6) having an anti-rotation orientation means (65) operatively connected to the spindle-nose anti-rotation block (42), when the tool holder (32) is placed into the Spindle (31) Tool holder retention means (61), while being rotationally aligned via the Spindle Tool holder orientation means (31) and secured via the Spindle's (32) Tool holder retention means (61), to the Machine tool spindle (3.1).
The following example is of the operational segment of NC programming code for the Selectable Character Multiple Stylus Orbital Engraving Tool (6) having the Pattern Disk Part 68.12 for the round hole (22.0) detail selecting and engraving the character “1” via the controller's variable 601 having a value of 1, with FANUC® G&M Code via the CNC Software Commands of a MAKINO® CNC Horizontal Spindle Machine Tool via the following FANUC© NC-Programming Code.
There are multiple methods that the G&M Code of the CNC Software Commands can utilize for a specific machine for circular and or helical interpolation. For example, first having the Cutting Feed Rate preset via F 10000; (for 10 kmm/min.=7,958 RPM) that could be used to control the motions of the CNC Machine Tool via the NC commands G91 G03 J-0.4; or G91 G03 X-0.4 Y-0.4 R0.4; G91 G03 X+0.4 Y-0.4 R0.4; G91 G03 X+0.4 Y+0.4 R0.4; G91 GO3 X-0.4 Y+0.4 R0.4; for one rotation of the extended individual multiple styluses (77-A) without lowering the extended stylus during its rotation, that could require a G91 GO1 Z-0.025 to push the extended stylus (77-A) further into the work-piece surface (21) to drill the extended engraving stylus(es) (77) for the next rotation if required, while there are variations of the above examples that will produce the same results such as FANUC's Helical Interpolation “B” option for the simultaneous helical motion of the 3 X-Y-Z axes.
There are other methods that the G&M Code of the CNC Software Commands can control the orbital CNC motion of the Selectable Character Multiple Stylus Orbital Engraving Tool (6) depending on the manufacturer of the CNC Controller and the manufacturers' installed options. For example a FANUC model of NC controller having the Conical Interpolation option installed could use the single command G91 G03 J-0.4 K-0.025 L6 F10000 to drill the extended engraving stylus(es) (77-A) toward the work-piece surface (21) Z-0.25 via 10 revolutions of the stylus(es), if required, while there are variations of the above example that will produce the same results.
There are multiple methods to engrave the orthogonal hole detail (22.1) consisting of first drilling down the round hole detail (22.0) then using the orthogonal X (37) and Y axes (38) motions to create the 4 squared corners of the orthogonal hole (22.1), drilling down one round hole detail (22.0) then using the orthogonal X (37) and Y axes (38) motions to create the 4 squared corners of the orthogonal hole (22.1), using the orthogonal X (37) and Y axes (38) motions to create the 4 squared corners of the orthogonal hole (22.1) while lowering the Z axis (39) toward the work piece, or any combination and or variations of the fore mentioned engraving detail methods.
