Here's the formulae: 1 second = 0.01666 minutes. 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 ...

This is a list of formulas used in face milling. This page explains the formulas for calculating the cutting speed (vc), feed per tooth (f), table feed (Vf), machining time (Tc), net power for face milling (Pc), and Kc values, giving examples to help your understanding. "Introduction to Machining" is a site where users can learn about machining.

CNC Turning Machining Time Calculation. To calculate cycle time for turning, the formula is also based on the original. For example, Machining Time = Length of Cut (mm) / Feed (mm per revolution) x Revolutions Per Minute, with the specifications being: Length = Tool Approach + Job Length + Tool Over Travels x Number of Passes.

Calculating feed rate: Unlike linear milling applications (face milling) where the tools cutting edge and centerline is identical, circular and helical interpolation feed rate is based only on the tools centerline (Vfi). The following formulas should be used to obtain the optimal running conditions. Milling Cutter Diameter Selection Calculation:

The facing is done in one cut when D (the Diameter of cutter) is bigger than w (the width of job).In this case the formula of Over-Run will be: Total Time for Milling : The time for milling the surface relies on the length of job(or workpiece). In the formula of Total Time for Milling,

Milling Formulas Speed (RPM) = (SFM x 3.82) / D Feed (IPM) = RPM x FPT x Z SFM (Surface Feet per Minute) = (RPM x D) / 3.82 IPT (Inches per Tooth) = (IPM / RPM) / Z MRR (Cubic Inches per Minute) = IPM * WOC * DOC AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf mf - steel = 1 mf - gray iron = .65

Time Period per Part Cycle Time Formula This formula is useful with longer cycle times like 30 minutes per part (which is the same as 2 parts per hour, but more on that later). Time Period per Part Cycle Time Calculation:

Here's a brief explanation of what is Material removal rate, the Material removal rate formula for milling, and the Material removal rate formula for turning. From month to month or quarter to quarter, as you buy more efficient (and expensive) machines, cutting tools and fixtures, you should be cutting more metal in the same time.

Hence the cutting time is the length divided by the linear speed: T = l V f = l F n × n. However, in most cases, we know the cutting speed and not the spindle speed. If we substitute n with the spindle speed formula, we can calculate the machining time directly: n = 12 × V c π × d. T = l × π × d 12 × F n × V c.

In the equation of Time for Cylindrical Grinding Cut Length of Cut = Length of job + Over-Travel where, Over-Travel equals to 0.5 cm. And Feed/Rev. = w/2 (for rough cut) or w/4 (for finishing cut). Where, w = Width of Grinding Wheel
