Embodiment Construction

[0015] The present invention is a ring knife numerical control cutting method of a sponge cutting machine, the steps are as follows: figure 1 Shown:

[0016] 1. Place the large piece of sponge on the workbench of the sponge cutting machine, and control the twisting degree of the ring knife; the twisting range of the ring knife: 270±270 degrees; that is, 0-540 degrees.

[0017] 2. Draw the cutting path of the ring knife and check whether the cutting graph of the ring knife is a closed curve. The specific steps are: select a point on the graph as the reference coordinate point, from this point to the end, if the coordinates of the point are the same as the reference coordinate point If the coordinates are consistent, it is a closed curve; if not, it is an open curve.

[0018] The calculation of twisting knife point for closed curve is as follows: image 3 As shown, the starting point of the closed curve is point i, the end point is point j, the coordinates of point i=coor...

Abstract

The invention relates to a calculation method of the automatic twisting points of ring cutter numerical control software, and the method comprises the following steps that (1) a large sponge body is arranged on a workbench of a machine tool; the twisting degree of a ring cutter is calculated in advance according to a path line which is generated by a product to be cut; (2) a closed curve of a ring cutter cutting graphic is detected; if the curve is closed, the twisting points of the closed curve are calculated; if the curve is not closed, the twisting points of the non-closed curve are calculated; and (3) after a result is calculated, cutting is carried out if the calculation is correct; and if the calculation is incorrect, step (2) is performed. The calculation method of the automatic twisting points of ring cutter numerical control software has the advantages that before processing, the twisting points of the ring cutter are calculated without a movement control card, meanwhile the positions of the twisting points are displayed, the positions of inappropriate twisting points can be changed by revising the order of the cutting paths before cutting, so that the impact on a product is prevented and the product quality is improved.

Description

technical field [0001] The invention relates to a calculation method for the automatic twisting point of a ring knife numerical control software. Background technique [0002] At present, the ring knife CNC software is based on the real-time calculation and feedback of the motion control card in the control of the twisting point. That is, the angle of the knife belt can be judged in real time during the cutting process of each line (straight line or curve). If the rotation angle of the knife is about to exceed the range, twist the knife 360 ​​degrees in the opposite direction, and then continue to cut with the twisting knife rotation. This ensures that the knife belt will not be twisted. This control method is simple, but the cut out product may not meet the requirements and be scrapped due to inappropriate twisting point. If before processing, the twisting point of the ring knife is calculated without using the motion control card, and the position of the twisting point ...
