Further information
The absolute translation component is modified by the following commands:
• TRANS
• G58
• CTRANS
• CFINE
• $P_PFRAME[X,TR]
The additive translation component is modified by the following commands:
• ATRANS
• G59
• CTRANS
• CFINE
• $P_PFRAME[X,FI]

G58 replaces the absolute translation component of the programmable
work offset for the specified axis, but the programmed additive offset
remains valid The reference is provided by the last settable work offset
called (G54 to G57, G505 to G599).
G59 replaces the additive translation component of the programmable
work offset for the specified axis, but the programmed absolute offset
remains valid
Offset values in the direction of the specified geometry axes
Comment
; Absolute translation component X10 Y10 Z10
; Additive translation component X5 Y5
→ total offset: X15 Y15 Z10
; Absolute translation component X20
+ additive translation component X5 Y5
→ total offset X25 Y15 Z10
; Additive translation component X10 Y10
+ absolute translation component X20 Y10
→ total offset X30 Y20 Z10
