4.5 “G174” RADIAL GROOVES ROUGH MACHINING/PRE-FINISHING CYCLE

Function G174 activates the rough machining and pre-finishing cycle for grooves on outer and inner

diameters, performed by a parting tool with less width at the bottom of the groove.

To run a G174 cycle the tool must be positioned with the reference edge on the start cycle point (tool

reset on left edge), at a distance of a diametrical millimetre from the part to be machined.

The feed speed used is that active when the operation is called up and must be specified in a block prior

to G174.
