there is also possibility to change the tool offset number in the grooving cycle in order to get both edges accuratelly. Sure, the grooving tool must have two offsets set up in the tool description.

hy dsandovalm check this out :

    NOEX LINK = 8 V1 = 123 V2 = 0.075 V3 = 0.5 ( tvf chamfer)

    T+LINK*101 G97 S+V1*320/55 M03 M08 M42   ( index rpm coolant )
        X100       Z-10                      ( rapid way above part, at target z )
        X60+2*2.5                            ( rapid at clearance )
    G01 X60-2*V3-1             F+V2 G95      ( cut a bit under chamfer end point )
    G00 X60+2*2.5                            ( x+ )
                   Z-10+2.5+V3               ( z+ )
    G01 X60-2*V3   Z-10        F+V2*1.25     ( 45*, feed a bit faster )
        X55                    F+V2          ( restore feed ) 
        X55.5                                ( break chip )

    G04                        F+60/V1*0.75  ( dwell for smooth finish )
        X50.3                                ( disengage cutting edge )

included so far :
... increased clearance approach ( good to avoid chips that are arround the part, and/or when rapids are not interpolated )
... mapped feeds ( go home sooner ? )
... parameterized chamfer ( for fine tuning )
... modulated ccs ( don't wave the spindle for short x travels )

future develop directions :
... rad comp
... 2nd offset & 2nd chamfer
... chamfering angle <> 45*
... chamfer or fillet
... ctr & custom parameters, linked to tool offset page or variables
... custom roughing and finishing toolpath
... monitoring available from above 4mm width
... custom shape
... etc etc etc / kindly
