straightness of and flatness of linear machines
straightness of and flatness of linear machines
(OP)
I wonder if any one can help me. I am a mechanical projects engineer with a linear motor manufacturing company.
I have been given the task of documenting the straightnes and flatness of our linear motor range using a laser interferometer.
Could any one tell me the best way of documenting a flatness and straightness value which can be repeatable and quoted to customers.
At the moment I propose to take straightness values of a number of linear motors with different system lengths and document this. However since I am looking for a single vaue to quote for such machines e.g XXmicro/m
I am bit concerned that for smaller lengths of systems not up to a metre am I introducing a factored error when I rounded it up to a metre.
Does anyone have a better idea of doing this.

Most probably you shold group families and go with tolerance per unit, Which is different for each group.
Small size motors are more accurate than bigger sizes.
