Detailed description
2.1 Axes
Application
The following can be machine axes:
• Geometry axes X, Y, Z
• Orientation axes A, B, C
• Loader axes
• Tool turrets
• Axes for tool magazine
• Axes for automatic tool changer
• Spindle sleeves
• Axes for pallet changers
• Etc.
2.1.3 Channel axes
Meaning
Each geometry axis and each special axis is assigned to a channel. Geometry axes and
additional axes are always traversed in "their" channel.
2.1.4 Geometry axes
Meaning
The three geometry axes always make up a fictitious rectangular coordinate system.
By using FRAMES (offset, rotation, scaling, mirroring), it is possible to image geometry axes
of the workpiece coordinate system (WCS) on the BCS.
Application
Geometry axes are used to program the workpiece geometry (the contour).
Plane selection G17, G18 and G19 (DIN 66217) always refers to the three geometry axes.
That is why it is advantageous to name the three geometry axes X, Y and Z.
