Problems solved by technology

The profiling processing method uses the profiling to control the relative motion trajectory of the tool and the workpiece to form the required surface shape. This method has a wide range of processing and can process workpieces with complex cross-sectional shapes, but the efficiency is low, the adjustment is complicated and the processing accuracy is poor; Special processing can be used for the finishing of non-circular parts, but the processing cost is high and the efficiency is low, and it is difficult to process workpieces with complex cros

Description

technical field [0001] The invention relates to a cutting processing control device and a control method, in particular to a cutting processing control device and a control method for a non-circular workpiece using a composite processing shaft. Background technique [0002] According to the rotation cycle of the main shaft, the displacement of the tool in the radial direction (lateral direction) of the workpiece can be controlled synchronously, and the workpiece with a non-circular cross-section shape can be processed. This processing method is called non-circular cross-section turning. At present, the methods for processing non-circular cross-sectional contours mainly include: profiling, special processing and CNC turning. The profiling processing method uses the profiling to control the relative motion trajectory of the tool and the workpiece to form the required surface shape. This method has a wide range of processing and can process workpieces with complex cross-section...
