Tutorial L2
Question 1:
A lathe tool is to be placed in a machine such that the plane se ng angle G is −20°, the
eleva on se ng angle H is −10°, and the roll se ng angle L is zero. Also, the tool-in-hand
angles are as follows:
1. The tool major-cutting-edge angle 𝜅 =30°
2. The tool major-cutting-edge inclination λs= 5°
3. The tool major-cutting-edge normal rake γn =10°
4. The tool major-cutting-edge normal clearance αn=5°
Calculate the working normal rake, working clearance angles, working tool major-cuttingedge inclination angle, and working tool cutting edge angle.
