Cutting Flat Surfaces
6.1 INTRODUCTION
Machining flat and contoured surfaces is performed with a single-point cutting tool during shaping for small- and medium-sized workpieces. For larger workpieces, a process called planing is used. For high production rate requirements, multipoint milling cutters are used in plain- and face-milling operations. Additionally, broaching is used for machining surfaces and internal contours to a high degree of surface quality.
6.2 SHAPING AND PLANING
Shaping and planing are machining by cutting processes that are used to produce flat and contoured surfaces. Their kinematics involves a reciprocating main (cutting) motion and an auxiliary feed motion. As shown in Figure 6.1, the cutting tool in shaping is ...
