Abstract

The article presents new highly effective methods of milling shaped surfaces, which are implemented on four-and five-coordinate CNC machines. For their implementation, three simultaneously coordinated movements of the machine’s organs are used. To implement the proposed milling methods on CNC machines, an electric drive is proposed, built on the basis of a Permanent Magnet Synchronous Motor (PMSM) with a vector control system with a proportional P-speed controller. For this purpose, an ecstatic control information and measurement system with zero static error is proposed. Comparative results of mathematical modeling of transient processes in electric drives with the standard and proposed control systems are presented.

Highlights

In mechanical engineering, controlled electric drive systems are widely used on CNC machines, while the requirements for drive and control systems are becoming more complex in terms of ensuring high speed and accuracy of working out control actions
One of the most effective ways to increase the durability of a cutting tool, as shown by recent research, is the constant displacement of the cutting edge tip during processing relative to the cutting surface, which leads to an increase in the active length of the cutting edge and a decrease in thermal stresses
Theoretical studies have confirmed a significant increase in processing productivity and tool life due to an increase in the number of teeth simultaneously involved in the work, increasing the length of the cutting edges due to their constant displacement, i.e., the working contact of the vertices of the cutting teeth relative to the cutting surface

Summary

Introduction

In mechanical engineering, controlled electric drive systems are widely used on CNC machines, while the requirements for drive and control systems are becoming more complex in terms of ensuring high speed and accuracy of working out control actions. Milling is one of the most productive processing methods due to the high concentration of cutting edges simultaneously involved in the cutting process, and at the same time high cost due to the high cost of equipment and tools.
