Geometric cutting simulation and verification

Abstract

In order to achieve the productivity gains described in section 1.2 of this book, it is required that machine tools operate with a reduced level of operator supervision. Ideally, the NC machine would be running in an unmanned mode. The use of simulation and verification is essential if programs are to be run with confidence in unmanned operation. While simple NC programs for prismatic parts can be tested ‘at the mill’, and then run repetitively on subsequent parts, sculptured surface parts are often ‘one of a kind’. This chapter presents various methods for performing the geometric simulation and verification of SSM-processes. The next chapter will present methods for simulating the physical cutting process, an important component for selecting cutting conditions that are both safe and efficient.
