Conversely if grinding is the bottleneck spending more time machining and exploiting the high finish capability of modern tooling may give best bang for buck. If you wanna make money you have to sweat the details. To sweat the details you need to know what's going on. If you don't know what's actually going on you can't know which details to sweat.

The Machining Time for Cylindrical and Internal Grinder is defined as the total time taken by Cylindrical and Internal Grinder to machine a Workpiece completely and is represented as t m = t s +d cut /V f or Machining Time = Spark Out Time+Depth of Cut/Feed Speed.Spark Out Time is the time required in passing the workpiece under the wheel, without resetting the depth of cut, …
(ii) Major Factors That Govern Machining Time The factors that govern machining time will be understood from a simple case of machining. A steel rod has to be reduced in diameter from D 1 to D 2 over a length L by straight turning in a centre lathe as indicated in Fig. 4.9.1. Fig. 4.9.1 Estimation of machining time in turning. Here, C Cp o L Tx ...
universal grinding machine that can machine a job up to 220mm diameter shaft. The grinding machine G17-22U was installed 20 years before when the plant was started. At beginning stage the plant had no expectation of producing 25 KW alternators. So the available grinding machine in the plant does not have a provision for tapper grinding.

my experience CAM time calculations are of limited use. i can set the timer on a CNC that measures actual run time. if job is 8 hours and CNC says it was running 4 hours it is of limited use. 10 operators make 100 parts over many years and nobody and i mean nobody does job in 4 hours cause it take more time that just machine time.
