sequence designated, whenever the part program is cycled.
3.4.10.12
Feed rate override.
A feed rate override control shall be
provided to allow manual adjustment of the programmed feed rate from zero to
not less than 120 percent of the programmed rate in either continuous
adjustment or in steps of not more than 10 percent.
