The present invention relates to a system and method for identifying and selecting multiple components to form a metal cutting tool assembly useful for a particular metalworking operation. More particularly, the present invention relates to a system and method for identifying and selecting multiple components to form a cutting tool assembly based on the compatibility of the components forming the desired cutting tool assembly and, optionally the machining operation to be performed by the cutting tool assembly.
There are a variety of metal working cutting tools for cutting or shaping a metal work piece. For example, one cutting tool is a rotating cutting tool that is generally employed in shaping or cutting a metallic work piece material. Such rotating cutting tools are commonly employed in machining geometries ranging from generally planar surfaces to complex grooves, recesses, holes or curved surfaces. These rotating cutting tools include those where the tool body and the cutting edge are formed from a single solid body (typically carbide type hard material), or those where an indexable insert formed with one or more cutting edges is secured to the tool body with a bolt or wedge mechanism and the like, such that it may be freely fitted and removed.
It will be appreciated that in order to determine an appropriate cutting tool assembly for a particular machining operation, it is necessary for a user, such as a manufacturing engineer or the like, to understand the relationships between the tool holder, one or more cutting tools, and potentially one or more intermediary components. In addition, the user must have an understanding of the properties of the particular material or materials being machined as well as the particular geometry or geometries being machined in such material. With the large number of available cutting tools, cutting tool components and systems, machined geometries and varying cutting conditions, it is extremely difficult for a user to configure the optimum cutting tool assembly configuration for a particular machining operation.
In the past, a user was required to search through and examine multiple catalogs supplied by various cutting tool manufacturers, or to search cutting tool databases, and to select a combination of cutting tool components therefrom with little or no information about the optimum operating parameters of each particular component. Such approach requires a considerable amount of time and labor and is particularly dependent on the experience and skill of the user and therefore may be unreliable and may only take into consideration a limited number of factors which may affect machining of the workpiece and efficiency of the machining operation. Furthermore, even when the tool body is of the same series, changes in its specifications also may change the cutting conditions due to the combination.
Thus, it would be desirable to provide a selection system and method that enables a user to select a cutting tool arrangement tailored to the user's specific equipment and particular machining operation that provides fast, accurate results independent of the skill level of the user.
As one aspect of the present invention a method of identifying a cutting tool assembly to a user is provided.

A method 30 of selecting a cutting tool assembly in accordance with an example embodiment of the present invention is shown in
In general, the method provides for the selection of a cutting tool assembly by a user, the cutting tool assembly being formed from at least two components, each selected from among a plurality of compatible tool components (e.g., without limitation, from a product line or in-stock inventory). Methods in accordance with the present invention offer a number of advantages over known methods such as previously described in the background section. Such advantages include, among others, that the time and expertise required in selecting one or more of the components of the cutting tool assembly is greatly reduced in comparison to previously known solutions. Embodiments of the present invention may be utilized by a user who is looking for a particular type of cutting tool assembly for a given operation or alternatively by a user that knows the end product they intend to machine but are looking for guidance in regard to selecting the cutting tool assembly needed to machine the desired finished product.
It is to be appreciated that the methods described herein are generally applicable to being carried out through the use of a computing mechanism, such as, for example, without limitation, a desktop or laptop computer, a handheld computing device (e.g., tablet computer, smartphone) or any other suitable electronic processing device. In example embodiments of the invention such devices may be used to selectively access databases stored online (e.g., in an internet based “cloud” storage) or may rely on locally stored data. The data can be stored in data base format in any suitable electronic media, such as a memory storage device, microprocessor, controller, PLC, RAM, ROM, ASIC, CDROM, DVD, and the like. The attributes or characteristics of the individual components of the tool assemblies 50, 60 and 70 are shown in
For example, the tool assembly 50 of

In another embodiment of the invention, the characteristic is indicated by the user inputting the desired characteristic into a field or fields of an input screen or selecting a desired characteristic from a drop down menu. It is to be appreciated, however, that any other suitable input arrangement may be employed without varying from the scope of the present invention.
Next, as shown in step 34, it is determined that at least a portion of a first set of characteristics associated with a first component of the plurality of tool components corresponds to the desired characteristic. In other words, a particular component or components having the desired characteristic associated therewith are identified in the database of components.
After such component or components are identified, a second component or components which are compatible (i.e., correspond, compatible with) the first component or components are then determined (i.e., identified) based on at least a portion of the characteristics associated with the second component or components (e.g., the “Connection Code”), as shown in step 36
Next, as shown in step 38, the first and second components are then associated or grouped together as a combination in response to the determination made in step 36. If characteristics of either of the first or second components indicate that there are other corresponding components (i.e., the complete cutting tool assembly has more than two parts, such as the assembly 70 shown in
In the example cutting tool assembly 50 shown in
Once a combination is completed, the combination of components is identified to the user as the cutting tool assembly, as shown in step 40. The combination of components may be identified to the user as a listing of the components and optionally particular details thereof (e.g., without limitation, part numbers, pricing information, availability, etc.) to assist the user in obtaining such components. Such listing may be provided on an output device (e.g., a display screen), via a hard copy paper printout or via any other suitable delivery method known in the art. In various embodiments of the present invention, the identification of the cutting tool assembly includes one or both of scale representations of each of the components of the cutting tool assembly and/or a scale representation of the assembled cutting tool assembly. Such representations may be provided as a visual for the user to confirm the components and/or assembly appear(s) as intended and/or as an electronic model which may be subsequently used by the user in programming the machine tool for which the cutting tool assembly is intended to be used.
It will be appreciated that the methods of the invention are not limited by the number of components which together form a cutting tool assembly and that the invention can be practiced with any desired number of components based upon the operating conditions of the cutting tool assembly. It will also be appreciated that, dependent on the number of potential components included in the database, the number of potential matching components or assemblies identified may be more than one. In such case, all of the assemblies located may be provided to the user as a listing. Such listing may be ordered in accordance with a preset ranking system based upon ready availability in inventory, metal removal rate or by a ranking selected by the user, e.g., cost.
In order to limit the number of potential matching components identified by the method, the method generally shown in
