CMM coordinate measuring machine
The coordinate measuring machine (CMM) is the most prominent example of the equipment used for contact inspection of parts. When used for CIM these machines are controlled by CNC. A typical three-dimensional measuring machine consists of a table, which holds the part in a fixed, position, and movable head, which holds a sensing, probe. The probe can be moved in three directions corresponding to the X, Y and Z Coordinates. For manual operation, the control unit is provided with joysticks, or other devices which drive X, Y and Z servo motors (AC/DC).

Mass manufacturing
The high quantity range (10000 to millions of units per year) is referred as mass manufacturing. A single product is produced in very large quantities. The situation is characterized by a high demand rate for the product and the manufacturing system is dedicated to the production of that single item.
