Blockwise oversize G52-Geo
G52 defines an equidistant oversize that is taken into consideration in
G810, G820, G830, G860 and G890.
Feed per revolution G95-Geo
G95 influences the finishing feed rate of G890.
„ Use surface roughness (V, RH), finishing feed rate (F)
and special feed rate ("E") alternately!
„ G39 is a non-modal function.
„ Program G39 before the contour element for which it is
intended.
„ G50 preceding a cycle (MACHINING section) cancels a
finishing oversize programmed for that cycle with G39.
Parameters
P Oversize (radius)
H P applies as an absolute or additive value (default: 0)
„ H=0: P replaces G57-/G58 oversizes
„ H=1: P is added to G57-/G58
„ G52 is a non-modal function.
„ Program G52 in the NC block for which it is intended.
„ G50 preceding a cycle (MACHINING section) cancels a
finishing oversize programmed for that cycle with G52.
Parameters
F Feed per revolution
„ Use surface roughness and finishing feed rate
alternately.
„ The G95 finishing feed rate replaces a finishing feed rate
defined in the machining program.
„ G95 is a modal function.
„ G10 resets a finishing feed rate set with G95.
