Machining with Five Axes<br />
– Guided Tool Tip<br />
CAM systems use postprocessors to<br />
generate fi ve-axis programs. In principle,<br />
such programs contain either all coordinates<br />
of the machine’s existing NC axes, or NC<br />
blocks with surface normal vectors. When<br />
machining with fi ve axes (three linear axes<br />
and two tilting axes*), the tool can stay<br />
perpendicular, or if desired, inclined at a<br />
predetermined angle to the workpiece<br />
surface.<br />

Regardless of what type of 5-axis<br />
programs you wish to run, the <strong>i<strong>TNC</strong></strong> <strong>530</strong><br />
makes all the compensating movements in<br />
the linear axes that result from movements<br />
in the tilting axes. The <strong>i<strong>TNC</strong></strong> <strong>530</strong>’s Tool<br />
Center Point Management feature<br />
(TCPM)—an improvement upon the proven<br />
<strong>TNC</strong> function M128—provides optimal tool<br />
guidance and prevents contour gouging.<br />
* The machine and the <strong>i<strong>TNC</strong></strong> must be adapted to these<br />
functions by the machine tool builder.
