Grinding, or abrasive machining, once performed on conventional milling machines, lathes and shapers, are now performed on various types of grinding machines. Grinding machines have advanced in design, construction, rigidity and application far more in the last decade than any other standard machine tool in the manufacturing industry.

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.

M.P. Jahan, ... Y.S. Wong, in Comprehensive Materials Processing, 2014. 11.14.5.2 Material Removal Rate. The material removal rate is defined as the amount of material removed from the workpiece per unit time. The material removal rate can be calculated from the volume of material removal or from the weight difference before and after machining.

Production Time Calculator The production time for a manufacturing process is primarily determined from the cycle time, but must also account for the defect rate, machine uptime, and machines used. Using these parameters, the run quantity, run time, down time, total production time, and production rate (parts/hr) will be calculated.

“There are two standard inserts, with different carbide and coatings. For inner diameter machining, you typically need a special insert. Today, the ID tool design takes a few weeks, plus the time it takes to manufacture the inserts and the toolholders.” Fortunately, the rollFEED turning process makes the cost-per-consumable lower than grinding.

Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.

Calculating the cycle time on a CNC, or computer numerical controlled, machine can help you maximize its efficiency. By looking at times through simulations, you can get the best estimates, but by comparing the part with others you have cut in the past you can also get an estimate without the assumptions the program may make for you.
