Correct CNC lathe knife method and accurate process for the knife
CNC lathes, CNC lathe knife method, CNC lathe tool setting process
NC machining, the workpiece coordinate system is determined, but also to determine the position of cutter location tool in the work coordinate system. That is often said that the problem of cutting tool. CNC machine tools, at present, the commonly used method is manual knife trial cutting.
1. CNC lathe CNC lathe knife knife basically the same as the first, after the work on good clamping jaw chuck, manual method of operating the machine, follow these steps: 1) the reference point return using the ZERO (reference point) operate the way back to the reference point to establish the machine coordinate system. At this time displayed on the CRT turret center (knife reference point) coordinates of the current position in the machine coordinate system. 2) to use the trial cutting tool has been selected outer circumferential surface of the workpiece car knife, keeping the size constant X, Z to retract, set the programming press zero key to display the X, Z coordinate values ​​are clear on the CRT screen to zero (ie, X0, Z0); then, stops the spindle, the measurement of the workpiece outer diameter D. as shown in picture 2. Then the workpiece face car knife, when displayed on the CRT X coordinate value - (D / 2), press the button to display the programming zero setting on the CRT screen, X, Z coordinate values ​​are cleared to zero (ie, X0, Z0), internal system to complete the set of functional programming zero. 3) establish the workpiece coordinate system tool tip (cutting tools site) current location on the programming zero (ie, workpiece origin) on.
