18 Note 018 ST 38 25 5B
Determine the feed rate for each operation (rough and finish). Remember that R.f/32N.
The cutting power, P, and calculate the cutting torque, Te.
Here, use the initial diameter Figure 2.1.
Considering the rough operation, determine the chip ratio, then calculate the shear plane angle.
092 The cutting conditions are given hereafter:
b. The friction angle
c. The shear force, F, and cutting force, F.
Calculate the spindle speed, M mm.
