I've been busy over the Christmas and New Year -
New computer - to replace the laptop - second hand tower.
Touch screen
Ball Screws fitted
Change everything to metric !!!!!!!!!!!!!!
New pulley system on the spindle drive to give equal steps up the pulleys and get maximum power out of the spindle VFD
Rewire all the auxiliaries (home switches and speed detection)
Wire in removeable touch pad.
Get the spindle speed control working relaibly and accurately.
Video camera in the milling spindle.
READY TO GO
NOW - I am cutting railway wheels - which means facing across a 6 or 7 inch wheel (3inch radius). If I am using Constant Surface speed, how do I set about it. I know how to get it working - I have "dabbled" a bit with it - but if you are to set up an accurate speed, how do you do it.
Does Mach know that X0 is the centre of the lathe and therefore can calculate the correct speed (given the material)
or - Do I have to set the lathe at a distance from X0 - say X25 - and then do an S command to set the speed at that distance - and Mach will then follow adjusting the speed as I move in or out.
or - Is it something different
HELP
