Cemented carbide cutting tool cutting movement in the role played by relative movement of the workpiece and cemented carbide cutting tool machining, divided into the main movement and feed movement.
1 main movement
The main movement is the most important cutting power consumption up to the movement, it is the relative motion of carbide cutting tool and the workpiece between students. The car, the main movement of the boring machine spindle rotation movement.
2. Feed motion
The feed movement of the additional movement is generated between the cemented carbide cutting tool and the workpiece in order to maintain the cutting performed continuously. FIG Vf is cars cylindrical longitudinal feed speed of movement, it is continuous. Infeed movement is intermittent.
3. Cutting layer
Cutting carbide cutting tool to cut through the removal of the workpiece in a single pass of the workpiece material layer. Workpiece rotation time, the cemented carbide cutting tool just moved from position I to Ⅱ, cut the workpiece material between the layer I and Ⅱ. The quadrilateral ABCD known as the nominal cross-sectional area of the cutting layer.
