Solution:
Determine the tangent of the angle at which the compound rest will be set when cutting a taper on a workpiece with the following dimensions:
- Outside diameter of the rod = 60 mm
- Length of the tapered portion = 80 mm
- Smallest diameter on the tapered end of the rod = 20 mm
Solution:
A cylinder rod is turned in two passes with the same spindle rpm, feed rate, and a half diameter. The cutting speed in the second pass is half compared to the first pass. Then the relation between the machining time of the first pass (Ti) and the machining time of the second pass (Tii) is:
