Product Description

CNC machining precision

Preventable factors affecting the dimensional accuracy of CNC machining precision


1. Processing technology


Most of the essential machining deviations are formed by different processing technologies. In order to ensure the basic processing technologies (such as "first rough then fine, first face then hole, first big face then small face" in milling numerical control processing, or "reduce the number of clamping, although select combined clamp" and other basic processing technology details in fixture application), the machining deviation caused by iron chips to aluminum parts is reduced For the aluminum is very soft, the iron scraps removed are very simple to form processing deviation. For example, in FANUC or Huazhong machining center, although the g83 instruction is used to drill deep holes, the scrap iron may be removed instead of the G73 instruction.


2. Numerical calculation in manual programming and automatic programming


3. Three factors of cutting: cutting speed VC, feed F, cutting depth AP and tool compensation


In simple words, under the condition of ensuring machining quality and tool wear, adjust parameters to fully develop tool cutting function, so as to achieve the highest cutting efficiency and the lowest machining cost.
