High Resolution Encoder Help
I need some help understanding encoder pulses I guess you would call it. My plan is to make a old Brown and Sharpe OD grinder into a cnc. So I am looking for a high resolution encoder. I have read that some of the new cnc grinders have 1,000,000 to 4,000,000 ppr encoders. How are they coming up with that? I can only find 4096 line ppr encoders. Does the computer multiply it, or how do they get 1,000,000ppr. I am looking for very fine movements. I found these encoders what do you think. http://www.fagor-automation.com/Line...ryEncoders.htm I also am looking at the www.machinemate.com control. One more thing the ball screw that I am looking at is 32mm with a lead of 4mm. I don't know if you need that info but there it is. Thanks
