asked Sep 23, 2022 in Machine Dynamics by Grayson (34.3k points)

The lost motion in CNC machine tool is on account of:

(a) Backlash in gearing

(b) Wind-up of drive shafts

(c) Deflection of machine tool members

(d) All of the mentioned

I got this question during an internship interview.

I'd like to ask this question from Programme using Least Square Technique in chapter Computer Aided Analysis and Synthesis of Mechanisms of Machine Dynamics

The correct option is (a) Backlash in gearing

Best explanation: The system must provide sufficient feedback and programming capacity to allow for backlash and lost motion between motor and load. Computer numerical control (CNC) of machine tools has embodied position control for a number of years.
