Speed and feed parameters for HEM slotting can be found marked as “Peripheral-HEM”

in the speed and feed charts for those series.

When facing, an endmill with a corner radius is suggested for the best finish.

Apply the adjustments below to the Peripheral Rough values from the application

guide below by tool category.

slot width

The width of the desired slot will determine the number of ﬂutes and endmill

diameter that should be selected. The following guide shows the minimum slot

width for each series of endmill.

Tech Info - Endmills Helical Ramp to Create an Entry Hole Using a helical ramp move to generate an entry hole is a preferred method to enter the middle of a part. The creation of the entry hole can be either a one-step or a two-step process depending on the number of flutes on the end mill. Tools with seven or fewer flutes only require one step; tools with more than seven flutes require two steps.
PAGE 3
Endmills - Tech Info Step 2: There are two common methods to enlarge an existing hole. Method #1 – Expand the entry hole from inside out. After reaching the desired entry hole depth in Step 1, and with the end mill still at depth, expand the hole outwards using the feed rate adjustment found in the chart below. Continue until the entry hole is enlarged to the expanded diameter shown at right.

Endmills - Tech Info If the axial depth of cut (ADOC) is ≥50% of the tool diameter: - Use the speed and feed values shown for the slotting operation in the speed and feed charts for the series of end mill being used. - If the tool projection exceeds 2.5 x the tool diameter, adjust the slotting speeds and feeds by the chart for long reach tool adjustments. Surface Finish Radial depth of cut (RDOC), or step-over, is based on the desired finish.
