So I work for a place that shuts down the machine every day. I am being told that I need to calibrate every time the controller is turned off. Is this correct?
I would say it depends on a lot of parameters :
If the program isn't finish, you can't continue the measure the next day accurately
On some old cmms, the homing position was a contact, with a repeatability about 0.1 mm.
If you use a rotary table, homing the machine = calibrate the rotary
Another parameter is the air bearings : if the air pressure is associated to the power supply, then the air bearings are in contact (with granite, bridge, quill), then can be damaged by dust, the guide ways can be damaged also.
And the last point is the risk of crash of the power supply card in the controller with a lot of on/off,on/off......
So I'm not sure that turning off the cmm is a good idea, except for the planet..
I agree. I am not a fan of turning it off. However they turn off the compressors and the controller every night. Got to save a buck. I have no real good augment for them to leave it on.
