May 20, 2019 It is often necessary for CNC people to determine how long machining operations will take to perform. You may be trying to determine which of two or more processes will be used to machine a workpiece - or you may just be wondering how long a machining operation will require to complete. Frankly speaking, the formulae related to calculating machining time are pretty simple to understand

Apr 20, 2021 The machining time in the lathe work can be calculated for a particular operation if the speed of the job, feed and length of the job is known. If “s” is the feed of the job per revolution expressed in mm per revolution and “l” the length of the job in mm, then a number of revolutions of the job required for a complete cut will be: l/s.

Apr 13, 2017 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.

Cutting speed is the rotational speed of either workpiece or cutting tool (based on which is rotating). It is measured by the unit—revolution per minute (rpm) and designated by N. For example, cutting speed in turning is 295rpm. In case lathe operations, such as turning, grooving, centre drilling, parting, etc., a cylindrical workpiece is used.
