In the process of turning precision parts of lathes, the rotation of the spindle forms the main movement in the cutting movement. The depth and feed of the turning tool on both sides of the turning workpiece form the feed movement and the knife movement in the cutting movement. .
- Main movement (headstock operation)
The main movement is the main movement provided by the machine tool or manpower, which promotes the relative movement between the tool and the workpiece, so that the front end of the tool is close to the workpiece.
(Lathe processing)
In a certain cutting processing method, the main motion has the highest speed and the highest power consumption, and generally there is only one main motion. It can be completed by the workpiece or by the tool; it can be a rotary motion or a linear motion.
- Feed movement (feed box operation)
The feed motion is the motion provided by the machine tool or manpower, which causes additional relative motion between the tool and the workpiece, and continuously throws the cut layer into the cutting to gradually cut out the entire surface of the workpiece.
- Knife-eating movement (slide box operation)
Knife-grabbing motion is a motion that controls the depth of penetration of the cutting edge when machining precision parts.
