The 5-axis CNC tool grinding machine with an integrated six-position wheel changer helps a shop reduce setup time, which is what shops spend the majority of their time performing, Kane said. Because job shops typically operate in a high-mix, low-volume environment, he added that they lose money when a machine tool is not running.

This agrees well with the observed time of 19 minutes. The actual machining time of 61 minutes is much higher than the 26 minute estimate. Many factors account for this. We did not have 2.5"x2.25" stock, so we had to machine several additional surfaces. We had to look for tools and spent time finding things. Basically, we were not well prepared.

Machining time in shaping can be estimated using the scheme given in Fig. 4.9.3 which shows the length of tool – work travels required to remove a layer of material from the top flat surface of a block in a shaping machine.

Time in seconds = time in minutes divided by 0.01666 When we divide 0.12143 by 0.01666, the result is 7.2887 seconds (just over 7-1/4 seconds). So we now know how long it will take to drill the hole. In order to use the formula, of course, you must be able to determine the feedrate in inches per minute (ipm).

When we estimate the cycle time, we usually ignore the time for rapid motions, but in small parts it can make a big difference. Example On a 0.2g, 20 m/min machine, if you drill these holes to a depth of 10 mm at a feedrate of 500 mm/min, the cutting time is 18 secs. and the rapid traverse time is 5.5 secs, almost 25 % of the total time.

For turning applications we do not need this formula since Spindle Speed is usually given in Constant Surface Speed (CSS), which uses SFM value directly. But if you still want to use RPM formula, then diameter value is the actual diameter of work piece. Calculating Spindle Speed (RPM): RPM= 12 x SFM 3.14 x Diameter
