Move the tool to workpiece depth: Press the
orange axis key and enter the value for the
position to be approached, e.g. –5. Confirm with
the ENT key
Confirm Radius comp.: RL/RR/no comp? by
pressing the ENT key: Do not activate the radius
compensation
Feed rate F=? Enter the positioning feed rate, e.g.
3000 mm/min and confirm with the ENT key
Miscellaneous function M? Switch on the spindle
and coolant, e.g.
M13. Confirm with the END key:
The TNC saves the entered positioning block
Enter
26 to move to the contour: Define the
rounding radius of the approaching arc
Machine the contour and move to contour
point
2
: You only need to enter the information
that changes. In other words, enter only the Y
coordinate 95 and save your entry with the END
key
Move to contour point
3 : Enter the X coordinate 95
and save your entry with the END key
Define the chamfer at contour point
3 : Enter the
chamfer width 10 mm and save with the END key
Move to contour point
4 : Enter the Y coordinate 5
and save your entry with the END key
Define the chamfer at contour point
4 : Enter the
chamfer width 20 mm and save with the END key
Move to contour point
1 : Enter the X coordinate 5
and save your entry with the END key
Enter
27 to depart from the contour: Define the
rounding radius of the departing arc
Enter
0 to retract the tool: Press the orange axis
key Z in order to get clear in the tool axis, and
enter the value for the position to be approached,
e.g. 250. Confirm with the ENT key
Confirm Radius comp.: RL/RR/no comp? by
pressing the ENT key: Do not activate the radius
compensation
MISCELLANEOUS FUNCTION M? ENTER M2 to end
the program and confirm with the END key: The
TNC saves the entered positioning block
