8.7.9  Straight and circular machining 
If you want to perform simple, i.e. straight or circular path movements or machining without 
defining a complete contour, you can use the functions "Straight" or "Circle" respectively.  
General sequence 
To program simple machining operations, proceed as follows: 
●  Specify the tool and the spindle speed 
●  Program the machining operations 
Machining options 
The following machining options are available: 
●  Straight line 
●  Circle with known center point 
●  Circle with known radius 
●  Straight line with polar coordinates 
●  Circle with polar coordinates 
If you want to program a straight line or a circle using polar coordinates, you must define the 
pole first. 
 
 
NOTICE 
 
Risk of collision 
If you retract the tool to the retraction area defined in the program header using either 
straight or circular path motion, then you must carefully ensure that a collision cannot occur 
as a result of the normal retraction logic. 
To be on the safe side, you should also move the tool back out of the retraction area again.
