Introduction

Shaped cutters are used to process parts with a complex shape, which includes rectilinear and curvilinear (radius) sections. Compared to conventional cutters, they provide shape identity and dimensional accuracy of the part, which depends mainly on the accuracy of the cutter, as well as high processing performance, which is achieved by simultaneously forming all sections of the shaped profile of the part and saving machine time. This work allows you to learn how to calculate the angles of prismatic shaped cutters, as well as design rails, get acquainted with the principle of their work and the need for use in production.

Conclusion

In this course project, we studied the basis of the metal cutting tool design and its elements. The design of cutting tools is one of the main directions in mechanical engineering. The quality and reliability, the operability of cutting tools used in mechanical engineering largely depend on the quality and accuracy of the obtained parts, the productivity of the processing process. When designing cutting tools, you need knowledge of the theoretical foundations of tool design and calculation, you need to be able to correctly determine the best structural elements of tools for these processing conditions and create their optimal design, taking into account operating conditions, know the main directions of their improvement, ways to improve reliability and efficiency, and imagine possible directions and prospects for the development of the cutting tool.
