5 Programming Tool Movements<br />
5.4 Path Contours - Cartesian Coordinates<br />
<strong>TNC</strong> <strong>360</strong><br />
Example for exercise: Circular arc connecting to a straight line<br />
Coordinates of the<br />
transition point from<br />
the line to the arc: X = 10 mm<br />
Y = 40 mm<br />
Coordinates of the<br />
arc end point: X = 50 mm<br />
Y = 50 mm<br />
Milling depth: Z = –15 mm<br />
Tool radius: R = 20 mm<br />
