Cutting Flat Surfaces
6.1 Introduction
Machining at 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 pro-
duce at and contoured surfaces. Their kinematics involves a reciprocating
main (cutt
