may feed into the tool. Feed rate Feed rate is the speed of the end mill’s movement correspondent to the workpiece. The feed rate is measured in inches per minute (IPM) and is the result of the cutting feed (IPR) and the spindle speed. Speed and feed considerations are crucial for optimal results.

Read MoreNow let's imagine that your spindle can't run faster than 5000rpm. We can still increase the feed rate by using a 3-flutes end mill and keep a constant chip load: 4500 = 3 x 0,3 x 5000. Based on this knowledge, we can now use tables that will allow us to calculate our feeds speeds and achieve an optimal chip load for any given material.

Read MoreJun 01, 2018 The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm + 10 mm binary mix is able to break the feed at a faster rate.
