This study proposed on Multi-Tip Lathe tool Structure, this tool can be installed in conventional lathe, in addition to reducing equipment, tool change cost, reducing the turning tool wear and improve the processing, especially for high-volume production the circumstancesthe research will combine the efficiency of this structure, the concept of automation equipment, combined with the PLC control system, to achieve a more accurate processing accuracy. In the traditional way to turning, but also demolition tool re-calibration center to replace the cutting tool, this mechanism do not need to change cutting tools to re-correction center, , knife-axis of the cutting force transmission, it has a linear relationship can be automatically corrected center, for the center axis of the workpiece to keep the blade cutting, turning soft workpiece can be reduced due to the interference leaving workpiece deformation.
In this paper is based on the Universal AC servo drives ASDA-AB can receive the parallel output of the encoder and the servo control structures to quickly get started. Combined with Programmable Logic Controller (PLC) control system, to install an AC servomotor to adjust the gear connected, adjust the tool and the central axis distance, it can automatically control turning tool diameter, do not have to through manual adjustment of the turning tool diameter, allows processing items can be made of the surface and the arc shape, the whole design toward Computer-Numerical-Control (CNC) development. The results of the theoretical deduction of the measurement processing of computer analog diameter, and mounting in the actual desktop lathe turning experiment, use the LabVIEW programming, curve fitting precision experiments.
