When considering these categories, productivity is the KPI category most closely related to mill efficiency. Productivity includes tons per man-hour, tons per run, changeovers, energy per ton, actual versus scheduled hours of operation, downtime, tons delivered per load, and loadout waiting time.

Within this range, an optimum water content for efficient grinding normally exists depending on the combined effects of a number of prevalent conditions such as pulp viscosity, mill retention time, internal friction and filling of the intersticies of the charge, material transport characteristics, and the mill physical design parameters.

Terms like trochoidal milling, high speed machining, adaptive milling, feed milling, and High Efficiency Milling are a handful of the names given to these cutting-edge techniques. With multiple techniques being described with somewhat similar terms, there is some confusion as to what each is referring to.

High-Efficiency Machining or High-Speed Machining is a machining methodology that focuses on extremely fast but light, low-pressure cuts. The result is an overall increase in the material removal rate. The milling technique is used where the radial depth of cut (RDOC) is less than 30% (usually 5-10%) of diameter and axial depth of cut (ADOC) is ...

This is extremely effective for using one tool to bring a block of material down to a final (or close to final) shape using high resultant material removal rates paired with the ability to create virtually any shape. High Efficiency Milling HEM has evolved from a philosophy that takes advantage of the maximum amount of work that a tool can perform.
Details 
High-efficiency milling is based on the "radial chip thinning" theory that's been around for a long time. The basic idea is to keep the tool cutting at an ideal chip load. To increase the metal removal rate, the stepover is substantially reduced from the typical 50% of tool diameter, but the feed rate is increased in order to maintain the ...

What is High Efficiency Milling. Now that we know what some of the obstacles are with running a high efficiency tool path, let's talk about what High Efficiency Milling is and how it works. HEM is a milling technique that helps spread wear of a cutting tool across the cutting edge, dissipate heat and reduce tool failure.
