Lubrication
A: is the process or technique of reducing wear between surfaces by using a lubricant between the surfaces.
B: is a special liquid that performs three main functions during machining. It lubricates the cutting action, carries off the heat generated, and flushes(冲洗) the chips(切削).
C: is the material being machined. It can be any material and any shape. In the machine shop it usually refers to round or flat pieces of metal ready to be machined.

举一反三
- Generally the function of lubrication is to form of a film of lubricant between any two surfaces that have relative （）， so that surfaces dont get touch with each other.
- The way to reduce （） is to build up a film of lubricant between any two surfaces that rub against each other.
- When machining three different cylindrical surfaces of a stepped shaft with the same turning tool, there are three operation steps, as the cutting parameters have been changed.
- A plastic is a synthetic material which can be molded into any desired shape and which uses an organic substance as a binder.
- Machining is the manufacturing in which the workers can remove the excess material of a part on a machine tool.
