Machining time Wikipedia

For example, in a drill press, machining time is when the cutting edge is actually moving forward and making a hole. Machine time is used in other situations, such as when a machine installs screws in a case automatically. One of the important aspects in manufacturing calculation is how to find and calculate the machining get price

3. CALCULATION OF MACHINE RATES FAO

In this paper, labor is included in the calculation of the machine rate. 3.2.1 Fixed Costs. Fixed costs are those which can be predetermined as accumulating with the passage of time, rather than with the rate of work (Figure 3.1). They do not stop when the work stops and must be spread over the hours of work during the year.get price
