Problems solved by technology

In the prior art, the processing time is usually determined after the actual processing operation of the CNC stamping and punching machine, which will waste a lot of time and occupy the use of equipment, or calculate the processing time as follows: first Calculate the walking time of the punching knife, then calculate the rotation time of the punching knife, and finally calculate the punching time of the punching knife. If the punching tool processing method is changed to punching knife walking and punching knife rotation in parallel, if the original time calculation method is still used, there will be a relatively large deviation, resulting in an error in the calculation time

Abstract

The invention discloses a concurrent control processing time virtual computing method of a numerical control pattern-punching machine, which comprises the following steps of: obtaining all processing pels in a processing material, and determining a processing sequence; sequentially traversing the processing pels, computing the traveling time, the rotating time and punching time of the processing pels, comparing the traveling time and the rotating time, and taking the larger value of the traveling time and the rotating time to compute the processing time; and finally, accumulating the processing time of all the pels, and outputting the processing time. According to the invention, the virtual processing time of the processing pels is computed according to the mode of the concurrent control processing pels of the numerical control pattern-punching machine; and by comparing the traveling time and the rotating time of the processing pels, and taking the larger time value of the traveling time and the rotating time as well as the punching time to compute the processing time, the processing time can be quickly computed in the application of the concurrent control mode of the numerical control pattern-punching machine, so that the accuracy of the virtual processing time computing can be improved. The method disclosed by the invention can be used for quick quoting of the processing expense of material to be processed in the numerical control pattern-punching machine.

Description

technical field [0001] The invention relates to the field of numerical control processing of leather and other materials, in particular to a virtual calculation method for parallel control processing time of the numerical control punching and punching machine. Background technique [0002] The CNC punching machine uses a driven punching knife to quickly impact on leather and other processed materials, thereby forming holes in leather and other materials. In practical application, the processing fee will be determined according to the processing time of the processing material. The longer the processing time, the higher the processing unit price. In the prior art, the processing time is usually determined after the actual processing operation of the CNC stamping and punching machine, which will waste a lot of time and occupy the use of equipment, or calculate the processing time as follows: first Calculate the walking time of the punching knife, then calculate the rotation ...
