Hi,

A friend of mine has an opthalmic lens surface genrator cnc lathe which is out of order for over a year. I was thinking about converting it to Mach. It is equipped with two linear axes controlled by servo motors and the the spindle also powered by another servo. There's a touch probe on it too which measures the mounted lens blank. I was wondering how to calculate the lens curves and the resulting g-codes. Is there any application software out there for programming these machines.
