Grinding is no exception. So, while Makino machining centers are helping manufacturers cut cost and time by minimizing non-cut time, setup time and tool-changing time, new technologies that combine grinding and milling in one setup in one machine are also reducing part cycle times by as much as 75 percent. Better, faster, more cost-effective.

Next, determine the inches per minute feedrate: 458 times 0.008 is 3.664 ipm. Finally, determine the time required in minutes: 3 inches of motion divided by 3.664 ipm is 0.8187 minutes. To determine the number of seconds, divide 0.8187 by 0.01666 - this comes out to 49.141 seconds. Fixed diameter machining versus changing-diameter machining.

What is the cutting time when 100mm workpiece is machined at 1000min -1 with feed = 0.2mm/rev ? (Answer) First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200 (mm/min) Substitute the answer above into the formula.

Grinding Wheel Speed Calculator: All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion.

Continuous Generating Grinding of Gears Only grinding can simultaneously deliver high surface finish and high precision geometry. Grinding is a metal cutting process that, due to innumerable cutting edges and high operating speed, can simultaneously deliver high material removal rate, superior surface finish and very precise geometry.

However, the cycle time in spark-out grinding process is not easy to be estimated. From such a viewpoint, in this study, using specific grinding force obtained by measured grinding force in the first spark-out pass, a calculating method of the real ground depth in continuous pass process is proposed. And, this method is experimentally evaluated.

In the actual CNC machining process, it is often required to determine how long one or several operations will take to complete, which is related to the machining cost and lead time of the end product. The calculation formula of CNC machining cycle time is easy, but the situation in the real calculation is much more complex, especially in different operations such as turning and milling.
