The existing part processing track is composed of continuous short line segments, which leads to the need for continuous start and stop, acceleration and deceleration, etc. when the cutting equipment is cutting along the processing track formed by short line segments, which will cause serious accidents on the machine tool. jitter
Moreover, when cutting, the feed speed of the cutting at the corner will be reduced to zero to ensure the stability of the movement, but in fact this method only slightly reduces the vibration of the machine tool. Due to the large load of the machine tool, even if the When the speed drops to zero, there will also be a strong vibration effect, and this method greatly increases the processing time and reduces the processing efficiency

The invention provides a method for determining a cutting path of a workpiece corner. The method comprises: determining an initial cutting path according to a numerical control machining program, performing fitting processing on the initial cutting path according to a fitting curve algorithm to generate a curve cutting path, determining a connection speed, determining operation parameters of the cutting equipment according to the connection speed and the curve cutting path, and controlling the cutting equipment to move according to the operation parameters. The invention further provides workpiece corner cutting path determining equipment and a storage medium. Through the method and equipment for determining a cutting path of a workpiece corner and the storage medium, an initial cutting path determined according to data of a to-be-processed part is subjected to fitting processing and the corner in the initial cutting path is fitted into the curve, so that when the numerical control system cuts the corner of the workpiece, shaking in the cutting motion can be greatly reduced, the cutting smoothness is improved, the cutting precision at a high speed is guaranteed, and the cutting efficiency is greatly improved.
Description
technical field [0001] The present application relates to the field of workpiece automatic processing control, in particular to a method, device and storage medium for determining a cutting path of a corner of a workpiece. Background technique [0002] With the precision of the original machine, the structure of the parts to be processed is becoming more and more complex. When the existing CNC machine tools are cutting parts, the stability of the CNC machine tools and other equipment directly affects the processing accuracy and efficiency. The existing part processing track is composed of continuous short line segments, which leads to the need for continuous start and stop, acceleration and deceleration, etc. when the cutting equipment is cutting along the processing track formed by short line segments, which will cause serious accidents on the machine tool. shake. Moreover, when cutting, the feed speed of the cutting at the corner will be reduced to zero to ensure the stab...
