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