4.7 “G175” / “G177” FINISHING CYCLE FOR RADIAL/AXIAL GROOVES
Functions G175 and G177 activate the finishing cycle for radial grooves (on outer and inner diameters)
and axial grooves (cut from right to left of the workpiece).
Only function G175 is described here; the description is also valid for cycle G177 (for which the rough
machining cycle is G176).
The tool position and reset follows the rules already described for rough machining cycle G174 which
should be consulted for further details.
The feed speed used is that which is active when the function is called up, and must be specified in a
block prior to G175.
The G175 cycle disables the tool radius offset (G40).
The parameters used are the same as for cycle G174, except for parameters F, L, P which are not used.
To activate the finishing cycle there are two syntaxes that can be used:
N...G175 A.. B.. C.. U/X.. W/Z.. Y.. H.. K.. Q.. D.. (R..) (S..)
In this case all the parameters are specified (see cycle G174).
N...G175 (C..)
In this second case all the parameters indicated in the last rough machining cycle that was run are used
except, (if specified) parameter C (tool width).
In both cases the corrector and the radius of the cutter used by the cycle are those active when G175 is
run.
