Straight or circular machining

When you want to perform straight or circular path movements or machining without defining
a complete contour, you can use the functions "Straight line" or "Circle" respectively.
General sequence
To program simple machining operations, proceed as follows:
● Specify the tool and the spindle speed
● Program the machining operation
Machining options
The following machining options are available:
● Straight line
● Circle with known center point
● Circle with known radius
● Helix
● 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.
If you use a straight or circular path movement to move the tool into the retraction zone
specified in the program header, you must also move the tool out again. Otherwise a
collision could occur as a result of the traversing movements in a subsequently
programmed cycle.
