7.1 Explaining Basic Cycles

FeedRate

A Feed block sets the feedrate for Line moves, arcs, and cycles that do not contain specifically programmed feed rates. Feed blocks also set the feedrate for modal moves. Add Feed blocks whenever necessary

Select the More Milling button, and then "Feed" from the pop-up menu.

Conversational format: Feed

G-code format: F[n]

A Feed block only alters the programmed feedrate, it does not activate the Feed Mode.

FeedRate (4th-Axis)

A FeedU block sets the feedrate for the 4th axis, U. If the U-axis is a rotary axis, the units for the FeedU block are degrees per minute (deg/ min); otherwise, the units are the same as in the Feed block.

Select the More Milling button, and then "FeedU" from the pop-up menu.
