Method for determining the path of CNC machining (CNC machining)

CNC machining feed processing path refers to the turning tool moving from the tooling point (or the fixed origin of the machine tool) until it returns to the point and completes the relative path through the processing process, including the relative path of drilling and non-drilling processing. The relative paths arranged in the system, such as CNC insert selection, cutting processing, cutting processing, etc. Most of the deep processing feed paths are carried out in the order of the parts. Therefore, the focus of clarifying the feed path is to clarify the initial processing feed path and the empty route arrangement under the empty route arrangement. For machining centers, clarifying the machining path generally follows the following hierarchical standards. It can ensure the precision and roughness of the workpieces of the processed product. Make the processing path as short as possible, reduce the time of empty space, and improve processing efficiency. Simplify the workload of numerical calculation methods as much as possible and simplify the processing procedure process. For some program flows that are reused multiple times, assembler should be used.

CNC blades processed by CNC should be clamped firmly and should not be too short in the elastic chuck. Before each cable cutter processing, check whether the CNC machining tool head meets the requirements. The cable cutter length should be determined according to the single-standard production depth level in the operating procedures. Generally, the deep processing of about 2 mm should be slightly better, and the elastic chuck should be fully considered. Whether to collide. In the event of deep manufacturing situation, you can communicate and communicate with the program process writer and use the cable knives twice as appropriate, that is, shorten the length by half to 2/3, and then wait until the production reaches a deeper position. Its extension can improve production efficiency. When using Gaso's mouth, you must especially master the depth of the lower blade and the length of the blade. Before installing the CNC machining tool head on the machine, wipe the smoothness with a cleaning towel clean, and remove the relative position of the machining center knife sleeve to avoid the iron pin damage and damage to the machining center.

The basic principle deviation of CNC machining is due to the choice of similar machining motion modes or similar CNC tool wheel trajectory. It is usually called the deviation of the basic principles of processing, because there are deviations in the basic principles of processing. If the fundamental deviations are within the allowable range, this solution is still valid. Processing deviation, installation deviation and damage during machine tool use will cause direct harm to the machining accuracy of product workpieces. The focus is on the rotational movement of the lathe spindle, the uniform linear movement of the machine tool guide rail, and the offset of the machine tool transmission gear. The keys of CNC machining of machining accuracy deviation include the accurate positioning of standard deviation relative error and processing by-production manufacturing deviation. When using machine tools to process product workpieces, be sure to select several geometric features on the product workpiece as the standard for precise positioning during the production process. If the selected precisely positioned reference object does not match the design reference object, a reference object orientation deviation will occur. The precise positioning surface layer of the part and the precise positioning components of the tooling fixtures form an accurate positioning pair. Due to the inaccurate by-product processing accuracy and the large deformation of the product workpiece part caused by the gap between the secondary middle, it is called inaccurate deviation of the by-product processing accuracy. When choosing the regression analysis method to process, production errors often occur with inaccurate positioning of the positioning pair, while errors are not easily discovered during tool radius compensation method.
