Research and Application of Tool Setting Instrument in CNC Machine Tool Based on Trigger Sensor Control
Taking the FANUC 0i-Mate system as an example,this paper studies the device for automatic tool alignment in CNC milling machines or machining centers:The tool alignment device.The tool alignment device uses a mechanical trigger sensor to control the contact between the spindle tool and the workpiece surface.The contact signal is transmitted to the CNC system through PMC,and the CNC system automatically sets the workpiece coordinate system by running a macro program.This tool pair device is suitable for measuring the length and diameter direction of CNC milling machines or machining centers,as well as detecting damage,with an accuracy of up to 0.001 mm.It can accurately and quickly compensate for the X,Y,and Z machining errors caused by tool wear,thereby ensuring the machining accuracy of the parts.
