A Rough Guide to Better Milling

Jul 04, 2006· High-feed milling involves taking shallow depths-of-cut at above-average feedrates — 400 ipm and faster. The main benefit of this technique is that it lets shops rough mill down closer to net part shapes, and do it as quickly as possible. Tri-Core builds plastic injection molds and machines 98 percent of its own mold bases.

Milling Parameters

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
