In the course design, a milling cutter is calculated for processing a given screw surface (chip groove). During the design process, the following issues were considered: calculation of the disk cutter on a computer, approximation of the curvilinear profile of the cutter, selection of calculation points, solution of the control problem of profiling the disk cutter. The graphic part of this project presents: the graphic construction of the cutter profile, the theoretical and actual profile of the screw chip groove in axial section, the working drawing of the two-angle cutter

Introduction

For the processing of grooves of parts with a helical surface such as spiral drills, end cutters, worm, face and tooth-cutting cutters, etc., the most common tools in the form of a body of rotation are disk spiky and naked cutters. Determining the shape of the profile of tools in their diametrical section is a difficult task, which is given quite a lot of attention in the theory and practice of designing a metal cutting tool. The profile of a disk tool for processing a complex surface depends on the profile of the part, the parameter of the screw surface, the position of the tool relative to the part and its overall dimensions.

The profile of the helical surface is obtained as an envelope of a number of successive positions of the surface of the tool during its relative movement. Therefore, the profile of the screw surface does not match the profile of the profiling tool (for example, a disk cutter) and is to be determined on a case-by-case basis. That is, a tool profile (profiling tool task) must be determined from a given shape of the surface being machined. However, you can also define the profile of the tool by defining the profile of the machined part (grading control task).

Solving the above problems is the main objective of this course project.
