Cemented Carbide Cutting Tools Motion

Cemented carbide cutting tools motion in the role played by relative movement of the workpiece and cemented carbide cutting tools machining, divided into the main movement and feed movement.
1. Main motion
The main motion 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 motion of the boring machine spindle rotation movement.
2．Feed motion
The feed motion of the additional movement is generated between the cemented carbide cutting tool and the workpiece in order to maintain the cutting performed continuously. Vf is cars cylindrical longitudinal feed speed of movement, it is continuous. Horizontal feed movement is intermittent.
3．Cutting layer

Cutting cemented carbide cutting tools 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 is the nominal cross-sectional area of the cutting layer. Actual cutting layer cross-section is a quadrilateral ABCE , △ AED is the cross-sectional area of the remaining on the surface of the processed.
