The disclosed innovation relates to manufactures and methods of fabricating manufactures for material removal purposes. More particularly, the innovation relates to a product that may be employed in a system that prepares surfaces or removes material (such as, for example concrete, asphalt, resins and the like), from a surface, for example, a surface such as a street may have material removed in relation to removal and/or placement or replacement of street pavement markers, traffic markings, lines, signals, wires such as embedded communication lines, and the like. For another example, a surface such as an industrial floor may have resins or any other type of flooring/flooring material removed. Methods disclosed may allow fabrication and configuration of a manufacture in advantageous manners.
Conventional and recent advances in the art may feature milling drum and drumless milling operations for material removal. In such operations, systems may employ various strike force implements. These implements as may be known in the art may be of permanent or replaceable design, and may by incorporated on picks or plates or affixed directly on drums. It is to be appreciated that replaceable design may be configured as a subassemblies or strike force implements affixed (in a permanent or replaceable manner) to a holder, and such holders attached to a pick or plate. It is to be further appreciated that the prior art includes pre-fabricated rounds and flats of such strike force implements. Such implements may be made from carbide compositions, sintered diamond compositions and the like. In other words, abrasive sections may comprise most any material conventional in the art, such as but not limited to, a polycrystalline diamond (PCD) material. It is to be appreciated that conventional use of these implements have not concerned themselves with orientation of the implement on a pick or plate or drum, and rather may have concerned themselves with the placement of the pick relative to a drum centerline (if at all).
The following presents a summary of the innovation in order to provide a basic understanding of some aspects of the innovation. This summary is not an extensive overview of the innovation. It is not intended to identify key/critical elements of the innovation or to delineate the scope of the innovation. Its sole purpose is to present some concepts of the innovation in a simplified form as a prelude to the more detailed description that is presented later.
The innovation disclosed and claimed herein, in aspects thereof, comprises articles and methods that may include configurations of abrasive elements for material removal systems. It is to be appreciated that most all systems may feature rotary motion that engages a plurality of abrasive elements to a surface being treated. A zone of contact, known as a working zone may be characterized as the material being removed and the portion of the material removal system in contact with the material being removed. A plurality of abrasive elements may be permanently or removably attached to a material removal system and the plurality of abrasive elements may be attached such that the rotary motion of the system moves the abrasive portion into contact with the material to be worked and provides a working zone that removes material in which the zone is placed. Multiple working zones may be present in different embodiments.
The innovation may provide advantages such that abrasive removal of material in a working zone may be more finely controlled and thereby provide a superior worked surface condition. Control may arise from aspects of the innovation such as for example an orientation control feature, a destructive interference effect feature, or a combination thereof. Aspects of the innovation include methods of manufacture that may create parametric or non-parametric sets with destructive interference effects when used as disclosed, and alternately, or in combination, creating an orientation control feature. It is to be appreciated that the orientation control feature provides advantage to both sinusoidal and other configurations of working edge designs that may assist in providing a superior worked surface condition.
To accomplish the foregoing and related ends, certain illustrative aspects of the innovation are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles of the innovation can be employed, and the subject innovation is intended to include all such aspects and their equivalents. Other advantages and novel features of the innovation will become apparent to those skilled in the art from the following detailed description of the innovation when considered in conjunction with the drawings, and it is intended that the innovation be constructed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
The innovation may take physical form in certain parts and arrangement of parts, various embodiments of which will be described in detail and illustrated in the accompanying drawings:
The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the subject innovation. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, structures and devices may be shown in block diagram form in order to facilitate describing the innovation.
While specific characteristics are described herein (e.g., thickness, orientation, configuration, etc.), it is to be understood that the features, functions and benefits of the innovation can employ characteristics that vary from those described herein. These alternatives are to be included within the scope of the innovation and claims appended hereto.
For embodiments as shown in the various figures, a manufacture may be comprised of a predetermined combination of a holder and a plurality of strike force implements. A manufacture also may be a configured strike force implement, and it is to be appreciated that the meaning shall be clear from the context of use. It is also to be appreciated that the innovation may be provided in embodiments for which a strike force implement may be permanently mounted to other elements of a material removal system, as well as embodiments for which mounting may be considered replaceable at one or more different levels. In other words, it is to be appreciated that abrasive element advantageously may be a removable or a non-removable abrasive element (either removable or non-removable from an assembly or removable or non-removable from a removable holder, with the holder and abrasive element considered to be an abrasive implement).

It is to be appreciated that as the power of a material removal system is most always transferred from the material removal device to the material of the surface being treated through a rotation around a principal axis (it is to be appreciated that the principal axis is parallel to an X-Axis as shown), of the material removal system. A slice or section of that system perpendicular to the axis may be considered to be a rotary plane (for example, the plane formed by the two dimensions of the Y-Axis and the Z-Axis). In context, a rotary plane may not be a true plane, as the rotary plane is to be considered to have a thickness 102. Thickness 102 may be considered to be the width of a material removal zone of a particular set of abrasive elements 104S (as shown in
A total working zone 106 may be as shown. In this example, the total working zone may include overlap between adjacent thickness 102 of one rotary plane to a next rotary plane. In other embodiments, a total working zone may be configured to have or not to have such overlap. In yet other embodiments, a total working zone may have a plurality of working zones separated by predetermined spacings. It is to be appreciated that in embodiments, the width of a set 104S may overlap or span one or more adjacent or intermittent sections, providing for a configurable pattern across a total working zone 106. In yet other embodiments, a plurality of working zones may occur at different radial distances from a principal axis of rotation, thereby providing more than one depth of material removed.
It is to be appreciated that while not shown, embodiments may comprise a multitude of chosen material working zone configurations. For example, various radial dimensions may be selected for such applications as providing a controlled work surface including a deeper groove for a laying of a wire, marker, road reflector, or other surface feature. In an embodiment, a center groove of 0.25 inches (or as may be desired), may be provided below an overall worked surface. Another example may be variable surface depth results for reflective inlays in a prepared road surface.

An abrasive implement may be shown to comprise a holder portion 204 and a plurality of abrasive portions 202. Holder portion 204 may also be fashioned to receive a plurality of permanently mounted abrasives 202. A holder portion 204 may have a tongue (or key) 206 that may fit a corresponding groove in a shoulder portion of a mating blade element (not shown). Holder portion may also have attachment mechanisms 208, for example, holes for screws, bolts, and the like (not shown). The permanently amounted abrasive 202 may be of various shapes, such as round, rectangular, etc. (as shown in various figures and discussed herein), and compositions, such as polycrystalline diamond (PCD), and the attachment of the abrasive may be according to most any number of methods known in the art. Notwithstanding that a person having ordinary skill in the art may know how to attach an abrasive 202 to a holder 204, the disclosed innovation includes aspects that have been found to provide advantages over known methods in the art. For example, abrasive 202 may be attached at a swept back angle 210 from a top plane. It is appreciated that this angle 210 may be chosen based at least upon a designated end use of various designs or predetermined application related to a variety of surface materials to be worked and removed. For a non-limiting example, angle 210 may be in the range of 0-45 degrees, or more particularly in the range of 10-30 degrees, relative to the horizontal plane. It is to be appreciated that angle 210 may create an axis Z of rotation for plurality of rounds 202. It is also to be appreciated that in this configuration as shown, plurality of rounds 202 need not be controlled for orientation in respect to rotation around axis Z (in contrast to other embodiments highlighting aspects of the innovation featuring orientation control, as will be discussed later. Further examples include having abrasive 202 be chamfered at each corner of the leading edge, as well as from the inclined plane edge towards the three vertical edges. It is to be appreciated that chamfering and other designs of abrasive 202 are to be considered to be within the scope of the innovation.

It has been determined that an embodiment providing for destructive interference may be advantageous for providing material removal in situations designed to have a finer finish. As disclosed in the embodiment of
In embodiments, N may be equal to an integer and may represent the number of crests in a first profile. In the embodiment shown, N = 4. It is to be appreciated in this example; 104N+1 will then have five crests. Thickness 102 may be seen as extending slightly outboard past the crests of 104N+1.
It is to be appreciated that destructive interference pattern approach may be controlled with choices of “N” and amplitude of the sinusoidal effect such that the surface of the material worked may have remaining ridge height and spacing controlled to most any desired ridge height and numbering. A specific example embodiment is shown in
While it is to be appreciated that the term "pairs' is used for ease of discussion, embodiments of paired abrasive elements need not be constrained strictly to an even number of abrasive elements in a rotary plane, but that a sinusoidal offset may be merely of one working abrasive element to a next in a particular rotary plane. In other words, the number of working abrasive elements in a rotary plane may be an odd number, rather than an even number, as long as at least two sequential working abrasive elements in a row are complimentary.

A method of manufacture may be demonstrated as follows. For a desired end application, a parametric constant may be determined. For the desired end application, a choice of a first number of crests of a selected sinusoidal pattern “N” and amplitude may be determined. A starting blank round may then be selected, and processing of the round in view of the selected attributes and parametric constant commenced, yielding a set, such as for example, 104S that provides destructive interference. It is to be appreciated that the processing may include parametric or non-parametric processing of an alignment feature. In other words, alignment features may be sized and selected parametrically or otherwise (for example, an alignment feature may be sized and selected based on a standard mounting size regardless of a chosen blank round diameter). It is further to be appreciated that for a desired end application, one or more of processing of a selected choice of “N”, amplitude, sinusoidal pattern, and alignment feature (or selected attributes) may be processed in a non-parametric fashion.
While emphasis has been placed on the embodiments of the innovation illustrated and described herein, it will be appreciated that other embodiments, and equivalences thereof, can be made and that many changes can be made in the described embodiments without departing from the principles of the innovation. Furthermore, the embodiments described above can be combined to form yet other embodiments of the disclosed innovation. Accordingly, it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative examples of the innovation and not as a limitation. It will be apparent to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as defined in the claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
