NC automatic programming method for laser processing machine

摘要

PURPOSE:To prevent a cut work from curving downward by its own weight by adding a microjoint at an optional position in a graphic drawn by CAD. CONSTITUTION:The CAD draws the graphic 1 to be worked on a display device 1. At this time, a working start point 25 is indicated. At the working start point 25, a boring work called piercing is carried out. This is carried out by providing a clearance based on a piercing line of length L from the working start point 25 to a working line 27. The working start point 25 is marked with a black dot and a working end point 23 is marked with 'x'. Consequently, when the work is cut by the working head of a laser working machine, the deterioration in working accuracy is eliminated, which is caused by the downward curvature due to its own weight of the other end of metal such as iron and stainless steel and the working head is prevented from colliding against the working head.
