The primary reason for orientation errors in cnc parts machining is the machining errors caused by the gaps and elastic deformation that occur in the transmission of the machine tool cnc parts machining process, as well as the orientation errors caused by factors such as the friction force that the tool head needs to overcome during the machining process. In the open-loop system, the orientation accuracy is greatly affected, while in the closed-loop follow-me system, the orientation accuracy depends primarily on the displacement detection
The machining accuracy error caused by the few errors of cnc parts machining. In the processing of CNC machine tools, because of external forces, heat generated in the processing and other external factors, the machine tool's few accuracy is affected, the few deformation of the parts machined in the machine cnc parts can lead to few errors. According to the study, the cnc parts machining few errors have two primary causes: internal factors and external factors. The internal factors that cause cnc parts machining few errors are the few errors caused by cnc parts machining own factors, such as cnc parts machining table level, cnc parts machining guide level and straightness, cnc parts machining things and fixtures few accuracy.
From the cnc parts machining long time data analysis and actual operation can be seen cnc parts machining machine tool positioning caused by machining accuracy errors. From the structural point of view, cnc parts machining processing errors are caused primarily by positioning accuracy, cnc parts machining feed system is the primary link affecting positioning accuracy. cnc parts machining machine tool feed system is usually composed of mechanical drive system and electrical control system.
