5 Programming Tool Movements<br />

5.3 Path Functions<br />

Overview of path functions<br />

<strong>TNC</strong> <strong>360</strong><br />

Input<br />

Function in Cartesian in polar<br />

coordinates coordinates<br />

Straight line at rapid traverse. G00 G10<br />

Straight line with a programmed feed rate. G01 G11<br />

Chamfer with chamfer length R. G24<br />

A chamfer is inserted between two intersecting straight lines.<br />

Circle center – at the same time a reference for polar coordinates. I, J, K<br />

I,J,K do not generate a movement.<br />

Circular movement in the clockwise direction (CW). G02 G12<br />

Circular movement in the counterclockwise direction (CCW). G03 G13<br />

A circular path can be programmed by entering:<br />

• Circle center I, J, K and end point, or<br />

• Circle radius and end point.<br />

Circular path with no direction of rotation defined. G05 G15<br />

The circular path is programmed by entering circle center and end<br />

point. The direction of rotation is taken from the last programmed<br />

circular movement (G02/G12 or G03/G13).<br />

Circular movement with tangential connection. G06 G16<br />

A circular arc is connected tangentially with the previously programmed<br />

contour element. The end point of the circular arc is<br />

entered in the part program.<br />

Corner rounding with radius R. G25<br />

A circular arc is inserted to connect tangentially both with the preceding<br />

and the subsequent contour elements.<br />
