Parts with high requirements for CCNC machining accuracy and surface roughness in Shenzhen 4 Parts requiring multi process machining in the processing process 5 Parts requiring expensive tooling equipment when using ordinary machine tools. The numerical control system is classified by control mode, iCNCluding control medium, input device, numerical control device, servo system, executive component and measurement feedback device: open loop control system (without feedback device), semi closed loop control system (angular displacement detection device), Closed loop control system (position detection device) CNC processing process content: select and determine the CNC processing content of the part 2 CNC processing process analysis 3 CNC processing process route design.
CNC processing procedure design and preparation of special documents for CNC processing are suitable for CNC processing: 1. The contents that cannot be processed by general machine tools should be taken as the priority; 2. The general machine tools are difficult to process, and the production efficieCNCy is high in the case of multiple varieties and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of cutting amount.
The coCNCept and content of CNC processing technology and its important role in CNC processing should be clarified, and the current CNC processing technology and processing technology should be comprehensively understood. The CCNC system can control the machine tool to automatically select and replace tools according to different procedures, automatically set tools, and automatically change the spindle speed and feed rate.
It can continuously complete drilling, boring, milling, reaming, tapping and other processes. Therefore, it greatly reduces the time of auxiliary processes such as workpiece clamping, measurement and machine tool adjustment, and has good economic effect for parts with complex machining shape, high precision requirements and frequent variety replacement.
