The efficiency of mashines is largely dependent on the characteristics of individual components included in their composition. This requires problem solving to achieve the required geometric precision parts, physical and mechanical properties of the surface layer. When designing tools raises questions of rational forms and geometry for a given surface quality. Significant impact on the surface layer has a front angle instrument whose value for a number of tools varies widely. To form a compression stress negative values recommended front corners. Thus, for tools made of hard alloys, mineraloceramics, cermets and superhard materials, most of the negative front corners are used to the extent and in the front corner of abrasive treatment may be close . The noted lack of knowledge of the mechanism of formation of chips, by cutting tools with large negative front corners, the methods of evaluation of a number of characteristics of chip formation and examples of implementation when comparing the calculated values with experimental when machining of lead parts. |
