5 Programming Tool Movements<br />
5.4 Path Contours – Cartesian Coordinates<br />
5-24<br />
To program a circular path CT with tangential connection:<br />
CT<br />
e.g.<br />
X 5 0<br />
Example for exercise: Circular arc connecting to a straight line<br />
Coordinates of the<br />
transition point <strong>from</strong><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 />
Part program<br />
COORDINATES?<br />

If necessary, enter also:<br />
• Radius compensation<br />
• Feed rate<br />
• Miscellaneous function<br />
Resulting NC block: CT IX+50 IY-10 RR<br />
Enter the coordinates of the arc end point, for example IX = 50 mm,<br />
IY = –10 mm.<br />
