21.2 There are three things that distinguish machining from other manufacturing
processes. First, the shear deformation process does not occur on a plane, but within a
zone. Second, the shear deformation that occurs in the shear zone, ano
23.2 The three modes of tool failure in machining are:
1. Fracture Failure
2. Temperature Failure
3. Gradual wear
23.5- The physical interpretation of the parameter C in the Taylor tool life equation is,
The intercept on the speed axis, a
22.7 The maximum distance between centers, or the maximum length of a work piece that can
be mounted between headstock and tail sock centers.
22.20 A mill-turn center can position a work part at a specified angel so that a rotating cutti
18.3 - Press working is often applied to sheet metal operations because the machines used to
perform these operations are called presses.
18.6 Increasing temperature affects the parameter in the flow curve equation by both strength
19.6 Draft in a rolling operation is when the work is squeezed between two rolls so that
its thickness is reduced by an amount, called the draft.
19.7 - Sticking in a hot rolling operation is when the hot work surface adheres to the roll

20.5 Notching involves cutting out a portion of metal from the side of the sheet or strip.
Seminotching removes a portion of the metal from the inter
