Chapter 15. Numerical Control Machining

15.1 Introduction

Manufacturing a part is the culmination of product design. We discussed the manufacturing and CAM processes in Chapter 1. A variety of manufacturing processes exists. The manufacturing engineer (process planner) selects a suitable manufacturing process depending on the part material and design tolerances. The process planner typically has a strong background in and knowledge of manufacturing processes. With this knowledge, the planner may request design changes from the design engineers to simplify part manufacturing and, as a result, reduce manufacturing cost. For example, machining a flat blind hole is harder and more expensive than machining a conical blind hole. The former requires ...
