2020-1-11 The finishing pass will be very shallow and the rougher will have opened up plenty of room for chip clearance. Consider using 2 or 3 flutes for roughing followed by 4 flutes for finishing in materials like aluminum. In harder materials that don’t need so much chip clearance, tools with as many as 10 flutes

2020-1-10 You should reduce the chipload for your finishing pass. However, you want to run an end mill with more flutes for finishing than for roughing. Therefore, your feedrate will be close to the same as roughing. For example, roughing in Aluminum you would want to use a 2 or 3 flute end mill. For finishing you would use a 3 or 4 flute end mill.

Feeds and Speed Calculator - Plunge Rate. In general, a plunge rate should be less than 50% of the feed rate, due to typical end mill design. End mills are designed to cut more efficiently in lateral directions, rather than vertically (like a drill bit). Therefore, a gentler plunge rate helps to keep the temperature down and avoid damage to the ...

2014-3-21 Keeping in mind that we don’t want to push the bit any faster than roughly 200ipm, if we wanted to use a 1/2 inch 4 flute bit, we could solve for spindle speed rather than feed rate. 0.01 x 0.5 x 4 x SpindleSpeed = 200ipm; SpindleSpeed = 10,000rpm; It’s helpful to make a chart so you can quickly find the numbers you are looking for.

More### Chip Load Chart - CNC Tooling - Cutter Shop

Chip load can be defined as the size or thickness of the chip that is removed with each flute per revolution. When material is machined the cutter must revolve at a specific RPM and feed at a specific feedrate to achieve the proper Chipload. There are also several factors to be considered when choosing the proper RPM and feed rate.
