Dependent Variables in Chipmaking

Ans: - Type of chip produced
- Force required to push tool into workpiece
- Energy required from the machine tool
- Temperature rise in the chip, tool and workpiece
- Surface finish of workpiece
- Surface integrity of workpiece

Idealized Model of Turning

Ans: Cutting Time, t = l / f N
Where: t is time in min.
l is length of cut in inches
f is feed in inches/rev.
N is RPM (rev. per min.)

Cutting Tool Definitions - Turning

Ans: Depth of Cut - d Distance tool is set to cut into the
workpiece (inches) Feed, or Feed Rate - f Distance tool
traverses per revolution of workpiece (inches per rev)
Rotational Speed - N Revolutions per min of workpiece, RPM
