In the NC programming software of five axis laser, when the relative path of laser cutting is loaded automatically, the position of laser head is generally set as the normal direction of the relative path of laser cutting, that is, the vertical direction with the laser cutting surface the beginning to the end. However, in some unique parts of the part, such as the inner arc with a smaller viewing angle. Laser head parts will inevitably cause interference.

According to the working experience of sicube fiber laser cutting NC programming software, it is impossible to maintain the normal orientation of laser head in laser cutting frame line under such conditions. If the way of detour is selected, the production processing of this part can be carried out.

If the angle of view of a B axes of the laser head is changed at the corner, the laser head has no normal position for laser cutting, but it can bypass the target of laser head impact.

However, in such an arc-shaped corridor, there will be diffraction phenomenon in several programming points, so it is necessary to carry out the A b axis changes at each programming point. Moreover, it must be considered that the angle of view of a B axes of all programming points on all arcs must be continuous smooth. If the angle of view of axis A axis B changes too much between the adjacent programming points, then in the specific laser cutting process, when the laser head rotates at a large angle, only moves at a very short distance (which will be only mm, even shorter), the pipe cutter controller will cause long-term laser cutting of coarse grains in this area Serious damage to the quality of laser cutting.

The sicube mobile phone software used by Xiaobian found that there is a very convenient way to solve this kind of situation. Only the a-axis b-axis visual angles of the laser head at the programming points before the intervention after the intervention must be adjusted. Then, the mobile phone software will automatically carry out the cutter radius compensation calculation with the angle of view of axis A B of the set two points as the starting ending angles, so as to ensure the continuous smooth connection between the two points 。 So it only solves the problem of detour, but also ensures the continuity of laser cutting.
