The knife point is the benchmark point for the workpiece to find the position of the workpiece coordinate system in the machine tool coordinate system after the workpiece is found on the machine tool.

The knife point can be selected on the workpiece or on the positioning of the positioning element, but the knife point and the workpiece coordinate point must have a accurate, reasonable, and simple position corresponding to the positioning of the workpiece coordinate point on the machine tool/(the workpiece coordinate point point Machine coordinates/). It is best to coincide with the workpiece coordinate point for the knife.

Change the knife point: The processing center has a knife library and an automatic knife change device. You can automatically change the knife according to the needs of the program. The sword changing point should not have any collisions and interference positions between workpieces, fixtures, tools, and machine tools when changing knives. The sword changing point of the processing center is often fixed.

Method of the knife:

Horizontal direction to knife/(x, y coordinate/):

/(1/) Loch leveraged percentage table pair knife: The point of the knife is the center of the cylindrical hole;

/(2/) Use borders -searching knife: round hole or benchmark edge

/(3/) Use a knife or test cut.

Z to the sword/(Z coordinate/):

/(1/) On -board knife: Use Z to the setter to the knife.

/(2/) The knife of the outside machine is pre -tuned+the on -board knife.

/(3/) Outside the machine to the knife and the knife: measure the diameter, length, blade shape and corner of the knife.
