Determination method of numerical control machining (CNC machining) path

The CNC machining feed machining path refers to the relative path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and completes the machining process, including the relative path of drilling. Paths and relative paths arranged in non-drilling operations, such as CNC insert selection, machining, machining, etc. Most of the deep processing feed paths are carried out in accordance with the outline sequence of the parts. Therefore, the focus of clarifying the feed paths is to clarify the preliminary machining feed paths and idle travel arrangements under the idle travel arrangement. For the machining center, the clear machining path generally follows the following levels of standards. It can ensure the precision and roughness of the workpiece of the processed product. Shorten the processing path as much as possible, reduce the time of idle routing, and improve the processing efficiency. Simplify the workload of numerical calculation methods as much as possible, and simplify the processing program flow. For some program flows that are used many times, assembler should be used.

CNC inserts should be clamped firmly and not too short in the spring chuck. Before each cable cutter processing, it should be checked whether the CNC machining head meets the requirements. The length of the cable cutter should be determined according to the single-standard production depth in the operation regulations. Generally, the deep processing of about 2 mm should be slightly better, and the elastic chuck should be fully considered. whether to collide. In case of deep-level manufacturing situation, you can communicate and communicate with the programmer of the program process, and use the cable knife twice as appropriate, that is, first shorten its length by half to 2/3, and then put it in a deeper position after manufacturing. Its extension, which can improve the production efficiency. When using the Kasuo Tsui, it is especially necessary to master the information about the depth of the knife and the length of the knife that must be used. Before the CNC machining tool head is installed on the machine, the smoothness is matched with each other, wipe it off with a cleaning towel, and the relative position of the machining center tool sleeve is also cleared, so as to prevent the iron pins from cooperating with each other from harming the accuracy and damaging the machining center.

The basic principle deviation of CNC machining is due to the selection of similar machining motion modes or similar CNC tool wheel paths. Often referred to as Machining Fundamentals deviation, it is due to deviations from the Machining Fundamentals. This workaround is still valid if the rationale deviations are all within the allowable range. Machining deviation, installation deviation and damage in the use of the machine tool will directly harm the machining accuracy of the product workpiece. The focus is on the rotational motion of the lathe spindle, the uniform linear motion of the machine tool guide rail, and the offset of the machine tool transmission gear. The CNC machining key of machining accuracy deviation includes the relative error of standard deviation and precise positioning of manufacturing deviation of machining auxiliary. When using machine tools to process product workpieces, several geometric features on the product workpiece must be selected as the criteria for precise positioning in the production process. Reference pointing deviation occurs when the selected pinpoint reference does not match the design reference. The precision positioning surface layer of the part and the precision positioning component of the fixture together constitute a precision positioning pair. Due to the inaccurate machining accuracy of the sub-production and the large deformation of the workpiece part of the product caused by the gap between the sub-production, it is called the inaccurate deviation of the machining accuracy of the sub-production. When the regression analysis method is selected for processing, the manufacturing error of inaccurate positioning of the positioning pair often occurs, while the tool radius compensation method is not easy to find errors.
