Material Cutting Speed Chart? - practicalmachinist

Mar 28, 2010 · H: is the speed for HSS, C: is for Coated (HSS +30%). The row below the material type is the Cutting Speed in Feet per Minute. For example Stainless Steel is cut at 60-90 fpm. For a .500 HSS cutter set your spindle speed from 458 to 688 rpm. Cutting Aluminum with a 1" Coated endmill - set your spindle 1528 to 3820 rpm.

How to Calculate CNC Spindle Speeds - webmachinist

In machining, spindle speeds, also called "cutting speeds", are extremely important for tool life, part finishes and over all part quality. This is especially true in CNC machining where the programmer must be able to calculate the spindle speed based on recommended "cutting speeds" usually given in either "Feet Per Minute" (FPM, U ...

How to Determine Cutting Speeds for Machining Tools

Since machining centers don't have gas pedals (nor gages that announce the current cutting speed), spindle rpm is the value we have to plug into the CNC program. To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter.

Spindle Speed - an overview | ScienceDirect Topics

The actual spindle speed to be set, which will maintain the quoted surface speed, depends on the diameter of the workpiece D (for turning and boring) or the cutter (for milling and drilling). Therefore, if a small diameter and a large diameter have to be machined at the same surface speed, then the smaller diameter must rotate quicker.
