A tolerance is the total permissible variation of size. where the tolerance is the difference between the limits of size. Range of tolerance grades that various machine processes may produce under normal conditions:

What angle tolerances can machine shops typically hold ...

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.
