What Kind of Factors Will Affect CNC Machined Accuracy?(1)

- Mar 07, 2018 -

Below are points to affect CNC machined accuracy during process

The position error of the parts

    The position error of the part is the deviation between the actual surface and the axis location relative to the ideal position, it’s mainly based on the machine tool transmission clearance and elastic deformation of the parts and head position errors caused by the friction of the service.

    In the open loop system, this effects of position error one machining precision is very big, but in the closed-loop servo system, it mainly depends on the accuracy of displacement detection device and system amplification coefficient, so the general effect is not too big.
