Cutting motion can be divided into main movement and feeding movement.
The main movement is the most basic movement that causes the workpiece and the tool to move relative to each other for cutting. The main movement has the highest speed and consumes the largest amount of power. In cutting motion, there is only one main movement. It can be done by the workpiece or by the tool. It can be a rotary motion or a linear motion. For example, the rotary motion of the workpiece on the lathe; planing and reciprocating of the workpiece when the planer is planed; the linear reciprocating motion of the planer; the milling cutter on the milling machine, the drill on the drill, and the rotation of the grinding wheel on the grinder are all during cutting The main movement (see Figure 1).

Feed motion is the continuous cutting of the cut layer to gradually cut out the entire surface. In other words, without this movement, you cannot cut continuously. Feed movements are generally slower and consume less power and may consist of one or more motions. It can be continuous or intermittent. Turning outside the circle, milling plane, planing plane, drilling, grinding outside the cutting movement of the garden as shown in Figure 1.
