Jan 15, 2001· His rule of thumb is to run at a chip load of 1 percent of cutter diameter or inch per tooth, whichever is less. He sometimes runs as high as ipt. Compared to a typical metal removal rate in aluminum of 3 cubic inches per minute per hp, this approach to chip load lets him achieve MRR up to 5 cubic inches per minute per hp.
I got a note recently from a GWizard user who wanted to know how to decide on best depth and width of cut when milling. It''s a great question. Most machinists, I suspect, use rules of thumb and habit more than anything else unless the situation dictates something in particular based on the dimensions of [.]
rules of thumb when deephole drilling are to reduce your rate of speed and feed, remove the bit more often from the material, and use lubricant whenever you can. Hole Depth to Diameter (times drill diameter) Ration Speed Reduction Feed Reduction 3 10% 10% 4 20% 10% 5 30% 20% 6 3540% 20% Speed and Feed Reduction (Based upon hole depth)
Aug 19, 2011· Wondering if there is a general rule of thumb for max milling depth? I''m designing a fiber optics cover that is about 4" inches tall. Due to design requirements it''s going to be machined aluminum. I''m debating on whether it should be designed in 2 .
General Rules of Thumb of Size Reduction 1. A specific type of machine (with fixed media, fixed operating conditions, and/or fixed equipment parameters) is most efficient in grinding a certain type of material with a certain range of feed size. 2. Size reduction over a large size reduction ration, for example (feed size/product size)>, is

Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
Jan 29, 2011· The mechanical irritation of topical ( cream or ointment) applied to diseased or traumatized tissues is a function of particle size. > a common '''' rule of thumb '''' is that particles should pass through 325 mesh sieve ( 44um) to minimise mechanical irritation. Example 6
