Purpose of Statistical Process Control (SPC)
The reason we take samples and perform SPC is to match part tolerances with
As process variables change, means and standard deviations change. (e.g., tool wear,

Feed rate is the rate at which the work is advanced under the cutter and is the distance a
cutting tool advances per revolution .
The feed rate generally should be as coarse as the setup will allow while still achieving a

Effects of heat treating
Hardness and strength are increased.
Shrinkage and distortion can occur in the parts.
Occasionally final machining must take place after to meet certain tolerances.
Scaling can occur where the high temper
