Drilling Speeds and Feeds Drilling Speeds and Feeds The speed of a drill is measured in terms of the rate at which the outside or periphery of the tool moves in relation to the work being drilled The common unit and term for this velocity is surface feet per minute, abbreviated sfm Every tool manufacturer has a recommended table of sfm values for their tools...
Rules of Thumb: Summary Chapter 0 RULES OF THUMB: SUMMARY Although experienced engineers know where to find information and how to make accurate computations, they also keep a min- imum body of information readily available, made largely of short- cuts and rules of thumb...
Profile milling Feed reduction to avoid shortened tool life Reversed up- and down-milling will expose the tool to alternating deflection and cutting forc By reducing the feed rate in the critical sections of the tool path, the risk for edge frittering is reduced, and a safer cutting process with longer tool life is achieved...
End Mill Depth Composition, rigidity, and size of the end mill greatly influence end mill deflection Rule of thumb for depth of cut: Standard Length of Cut for 2,3 and 4 Fute End Mills: End Mill Size Minimum Corner Radius Maximum Depth of cut End Mill Size Stub Regular Long Extra Long0625...
Cement mill A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cementMost cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills...
'Rule of thumb' A rule of thumb is a means of estimation made according to a rough and ready practical rule, not based on science or exact measurement What's the origin of the phrase 'Rule of thumb'? The 'rule of thumb' has been said to derive from the belief that English law allowed a man to beat his wife with a stick so long as it is was no thicker than his ....
Rock Crushing Rule of Thumb If the coarse feed size is reduced, the circuit efficiency will approach that of the stage-crush and ball mill circuit Hence, if the JKDropWeight test Axb parameters (a measure of rock competency) are less than about 40, then secondary crushing is worth considering Source Ausenco; More: Grinding Rule of Thumb Froth Flotation Rule of Thumb...

Depth of cut help, please Sep 16, 2009· Depth of cut is more a function of machine power and more importantly rigidity of the setup 1/2 the diameter of the cutter is a good rule of thumb as a maximum for milling say a pocket Take as big a cut as the setup will allow Using the hand cranks gives you instant feedback and the sound of the cut determine how much can be taken in one pass...
Grinding Rule of Thumb Here is a list of Rules of Thumb often used in Grinding Circuits: Fine ore bins (or stockpiles) that provide feed to the grinding circuit should have a capacity equal to 30 hours of processing Source: Northern Miner Press Grinding is a low-efficiency, power-intensive process and typically can account for up to 40% of the direct operating cost of the mineral processing plant Source: Callow ....
Peck Drill Depth, Rule of Thumb? Dec 30, 2005· Are there any guidelines or rules of thumb for determining pecking depth (Q) on a G83 cycle in a VMC? Is it a function of the drill diameter? I'm drilling 3/16" holes 25" deep in 303SS with a parabolic flute drill and flood coolant At Q=01 that's a lot of pecks...
