A G92 code will reset the axis register position<br />
coordinates to this position.<br />
For a program to run on a machine, it must contain the following<br />
codes:<br />
M03 To start the spindle/cutter revolving.<br />
Sxxx The spindle speed code to set the r/min.<br />
Fxx The feedrate code to move the cutting tool or<br />
workpiece to the desired position.<br />
TAPERS/BEVELS/ANGLES<br />
• The X Z coordinates of the small diameter, the large<br />
diameter, and a feedrate must be programmed.<br />
• Z moves the cutting tool longitudinally away from the end<br />
of the workpiece.<br />
• Z- moves the cutting tool along the length of the workpiece<br />
towards the chuck (headstock).<br />
• X moves the cutting tool away from the work diameter.<br />
• X- moves the cutting tool into the work diameter.<br />
