N50 TRANS X10 Y10 Z10 ; Absolute translation component X10 Y10 Z10
N60 ATRANS X5 Y5 ; Additive translation component X5 Y5
→ total offset: X15 Y15 Z10
N70 G58 X20 ; Absolute translation component X20
→ total offset X25 Y15 Z10
N80 G59 X10 Y10 ; Additive translation component X10 Y10
→ total offset X30 Y20 Z10

Further information
The absolute translation component (coarse offset) is modified by the following statements:
● TRANS
● G58
● CTRANS
● CFINE
● $P_PFRAME[X,TR]
The additive translation component (fine offset) is modified by the following statements:
● ATRANS
● G59
● CTRANS
● CFINE
● $P_PFRAME[X,FI]
