The degrees of the irregularity can be controlled by modifying the feed control pattern, for example the magnitude of the feed rate, {HEAD ~ the time pitch} between {TAIL ~ the high rate feed} and the low rate feed, and by controlling the operation carefully, the roughness of the irregularity can be restrained to a certain level
