feed rate to generate the required prole. During shaping, the cutting tool is
responsible for the main cutting motion while the workpiece feeds to gen-
erate the prole of the cut surface. During milling of contours, the vertical
milling cutter (end mill) rotates (main motion) while the workpiece feeds in
accordance to the required prole.
1.3.1.3 Form and Generation Cutting
During thread cutting, the tool having the thread form (form cutting) is
allowed to feed (generation cutting) axially at the appropriate rate while the
workpiece rotates around its axis (main motion), as in Figure 1.7. Similarly,
Machining ...
