Machine cutting by relative movement between the tool and the workpiece to achieve, its movement can be divided into surface and supplementary motor sports categories. Exercise is formed on the surface of the workpiece to obtain the desired surface shape and dimensions Machine Tool ck50, which includes the main motion, the feed movement and cut motion. Main sports play a major role in the release is the excess material from the workpiece blank exercise, it may be a rotary motion artifacts (such as turning), linear motion (as in the gantry planer planing), may also be rotational movement of the tool (eg milling and drilling) or linear motion (such as slotting and broaching); feed movement is part of the tool and the workpiece to be machined moved towards the cutting motion to proceed, such as when turning cylindrical turret slide plate along Machine Tool The movement and the like; cut motion is a certain movement of the tool cutting depth of the surface, and its role in each cutting stroke cut from a certain thickness of the material surface, such as when turning a small cylindrical turret transverse cutting movement.
