Feed rate reduction distance ratio at cutting start of a very-deep-hole drilling cycle/decremental very-deep-hole machining cycle

Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.
What it does

Feed rate reduction distance ratio at cutting start of a very-deep-hole drilling cycle (blind hole, through hole)

Set the feed rate reduction distance from the reference point at cutting start of a very-deep-hole drilling cycle (blind hole, through hole) during the point machining. Specify the ratio with respect to the drill diameter. If the nominal diameter of the drill is D, the feed rate reduction distance L at cutting start is calculated using the following calculation expression: L = D × D58/100 The feed rate is reduced by the ratio specified in D54 (feed rate reduction ratio at cutting start) by the distance L from the reference point (R). R L = D × Feed rate reduction
