The process of the CNC lathe tool setting is simply: first adjust to the manual gear, then hand to the position of the workpiece, remember the coordinates, retreat to the end of the workpiece, and then feed the X axis about 1mm, then the hand crank The inner diameter is measured, so that the X axis is correct. Note that when the outer circle is finished, the X axis cannot be moved, and then the end of the workpiece is retracted. The end face can be cut, the X axis is manually cut, and then Continue to hand crank X axis to exit, this is the Z coordinate, generally Z = 0.

There are three main methods of tool setting for CNC lathes:

1, the general knife

Generally, the tool setting refers to the manual tool setting using the relative orientation on the machine tool. Let's take the Z-direction tool as an example to illustrate the method of setting the knife.

After the tool is installed, first move the tool to manually cut the right end surface of the workpiece, then retract the tool along the X direction, and input the right end face and the machining origin interval into the numerical control system, that is, complete the Z-direction tool setting process of the tool.

Manual tool setting is the basic tool setting method, but it is still the "cutting-measure-adjustment" tooling form that does not jump out of the traditional lathe, taking up more time on the machine. This method is relatively backward.

2, the machine outside the knife to the knife

The essence of the outer cutter is to measure the interval between the imaginary tool tip point and the tool table reference in the X and Z directions. Using the off-machine tool setting tool, the tool can be pre-calibrated outside the machine tool, so that the tool length can be input by inputting the corresponding tool compensation number after the machine is installed.

3, active tool setting

The active tool setting is completed by the tool tip detection system. The tool tip approaches the contact sensor at the set speed. When the tool tip contacts the sensor and announces the signal, the CNC system immediately records the coordinate value of the moment and actively corrects the tool. Compensation value.
