8 Cycles<br />

8.1 General Overview<br />

Dimensions in the tool axis<br />

8-4<br />

The dimensions for tool axis movement are always referenced to the<br />

position of the tool at the time of the cycle call and interpreted by the<br />

control as incremental dimensions. It is not necessary to press the<br />

incremental key.<br />

The algebraic signs for SETUP CLEARANCE, TOTAL HOLE DEPTH and<br />

JOG INCREMENT define the working direction. They must be entered<br />

identically (usually negative).<br />

Customized macros<br />

The machine tool builder can store additional cycles in the control<br />

memory. These cycles can be called up under cycle numbers 68 to 99.<br />

Information on these cycles is available <strong>from</strong> the machine builder.<br />

The <strong>TNC</strong> assumes that at the beginning of the cycle the tool is positioned over the workpiece at the clearance<br />

height.<br />
