Comparison of old PAL programs and PAL2020

Complete table with a comparison of “PAL2008/PAL2012” and “PAL2020” (status spring 2023):
PAL2008/PAL2012 PAL2020 Meaning Where is it found?
G41 G45 D G41 G45 DL Linear tangential approach Milling and Turning with driven tools
G42 G45 D G42 G45 DL Linear tangential approach Milling and Turning with driven tools
G40 G46 D G40 G45 DL Linear tangential departure Milling and Turning with driven tools
G41 G47 R G41 G46 RR Tangential approach on a quarter circle Milling and Turning with driven tools
G42 G47 R G42 G46 RR Tangential approach on a quarter circle Milling and Turning with driven tools
G48 G40 R G40 G46 RR Tangential departure on a quarter circle Milling and Turning with driven toolsn
G17 G15 Svivelling and Resetting the machining level Milling Level selection
G17 G15 G17 IP3 Level selection face end with virtual Y axis Turning with driven tools
G17 C G15 G17 IP0 Level selection face end with polar coordinates Turning with driven tools
G17 Y C G15 G17 IP5 CM Level selection face end with real Y axis Turning with driven tools
G18 G15 G18 TURN Level selection for Turning Drehen mit angetr. Werkzeugen
G19 X G15 G19 IP1 DM Level selection surface area with virtual Y axis Turning with driven tools
G19 C G15 G19 IP0 Level selection surface area with polar coordinates Turning with driven tools
G19 Y X G15 G19 IP5 DM Level selection chord area with real Y Axis Turning with driven tools
G86 M1 ; G86 Radial recessing cycle Turning, not automatically “translatable”, therefore commented out here with M1 ;. The cycle must then be reprogrammed.
G88 M1 ; G88 Axial recessing cycle Turning, not automatically “translatable”, therefore commented out here with M1 ;. The cycle must then be reprogrammed.

 

Other changes do not necessarily require the revision of existing programs, but may have an impact in the simulation:

 
PAL2008/PAL2012 PAL2020 Meaning Where is it found?
G0 X Y Z G0 X Y
G0 Z		 Positioning logic for G0 and G10 omitted Milling
T S F M13 T M6
S F M13		 Tool change with M6
In SYMplus™, however, T still triggers
the change directly, M6 remains optional		 Milling
