Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tool setting blocks, in particular to a tool setting block for a contour knife. Background Art
[0002] At present, tool setting instruments or physical tool setting are generally used to obtain the offset distance of the tool in the X and Z directions, and then the tool is used to perform linear or circular interpolation on the workpiece. The key to tool presetting is to determine the motion trajectory of the tool nose center, because only by determining the actual working quadrant of the tool, the radius of the tool nose arc, and the accurate position of the tool relative to each point of the workpiece shape can qualified parts be processed.
[0003] In the process of CNC turning tool processing, most tools can directly find the center of the nose of the profiling tool, but it is difficult to find the center of the nose of the profiling tool as a profiling tool. Taking the profiling tool with a full angle of 35° as an example, since the blade of the profiling tool cannot directly contact the reference surface of the workpiece, if it directly contacts, it is easy to damage the workpiece. Therefore, it is impossible to accurately measure the X-direction and Z-direction offset distances between the profiling tool and the reference surface of the workpiece during tool alignment. It is necessary to visually measure the difference between the actual size and the required size repeatedly, and constantly adjust the X-direction or Z-direction offset distance of the profiling tool, which is time-consuming and laborious; and it is easy to cause tool piercing or collision accidents during the adjustment process, which increases processing costs and reduces processing efficiency.
