Defining a complete circle

Bolt-hole circle center X

(absolute): Coordinate of

the circle center in the X axis.

Bolt-hole circle center Y

(absolute): Coordinate of

the circle center in the Y axis.

Bolt-hole circle diameter:

Diameter of the bolt-

hole circle.

Starting angle:

Polar angle of the first machining

position. Reference axis: Major axis of the active
machining plane (e.g. X for tool axis Z). You can enter
a positive or negative value.

Number of positions:

Total number of machining

positions on the circle.

Workpiece surface coordinate

(absolute ): Enter

Z coordinate at which machining is to begin

If you have defined a workpiece surface in Z not equal to
0, then this value is effective in addition to the workpiece
surface Q203 that you defined in the machining cycle.

Example: NC blocks
