The firms Sandvik Coromant and Walter instruments choice algorithmization

This article describes the typical algorithms for choosing modern tools made by foreign firms Sandvik Coromant and Walter. The use of modern tools is effective on both new and old equipment. Algorithms ensure orderly operation of engineers in the development of new or upgrading old processes, and may also be useful for students enrolled in the specialty "Mechanical Engineering". The use of modern tools is effective on both new and old equipment. Correctly chosen tool make it possible for you to quickly recoup the cost of new equipment and significantly improve the work of the old equipment. Currently, all cutting tools can be divided into the following groups: a) a solid; b) composite; c) assembly; d) modular (dial-up). In composite cutting tools and parts theholders are attached permanently. For example, the attachment can be blocked by welding or soldering. At modular and modular cutting tools and parts are detachable. In those parts of the modular tool there are separate assembly units (modules) with standardized mounting surface. Thus one and the same cutter head may be attached to a holder (mandrel housings) of different configuration and function. The choice of the cutting part of such tools includes determining the shape and size of the indexable insert (SMP), the geometry of its front surface, corner radius and tool material. Selecting the holder (mandrel body) includes determining its type and size. It is necessary to take into account the possibility of technological equipment (type and size of the mounting surfaces of the tool holder and tool spindle).After selecting the tool it is necessary to determine working regimes
