Equation 2 will provide a guideline as to the maximum speed when drilling standard materials. The optimum speed for a particular setup is affected by many factors, including the following: 1. composition, hardness, and thermal conductivity (k) of material 2. depth of hole 3. efficiency of cutting fluid 4. stiffness and condition of drilling machine 5.
This RPM formula can be used for other machining operations as well. Let's put this formula to work in calculating the RPM for the machining example below. Use the recommended cutting speed charts in Table 4. A cut is to be made with a highspeed steel (HSS) tool on a 2inch diameter piece of 1018 steel with a brinnel hardness of 200.
Sep 25, 2018· Calculate the distance to the object by multiplying the height (or width) of the object by 1000 then dividing by the number of Mils that the object spans. For example: a six foot tall object (2yards) which is eight Mils in size is 250yards away. 2 x 1000 / 8 = 250.
n – shaft rotation speed, s1 ... The first of summands of head calculation formula represents drop of pressures which should be overcome in the process fluid pumping. Occasionally, pressures p 1 and p 2 may coincide, with head created by pump spent on lifting fluid .
This formula is much better than the antiquated Greenhill's formula. Stability value should be in the range of to to ensure bullet stability. Don Miller and Dave Brennan (editor of Precision Shooting ) have also been kind enough to let me host his stability paper on my exterior ballistics bibliograpy page.
Production calculation of spinning is one of the principle tasks for production manager who is responsible in spinning floor. Maximum time textile engineers forget the common spinning production calculation formula. In this article just I want try to give production calculation formula in .
Speed Loss Calculation Explanation [KI] This article has been written to better explain how speed loss should be calculated for a piece of equipment or line. The calculation of speed loss can be slightly confusing and to ensure that it is done correctly consider the following example:
Mar 12, 2019· The engine torque reaches its peak value at a speed where it is most efficient. In other words, the engine efficiency is at the maximum at a speed where it produces its peaktorque. If you raise the engine above this speed, its torque starts to decrease because of the increased friction of the engine's moving parts.
You can calculate the hourly production rate on your own. No special software is needed to perform the calculation. The production rate can change from day to day if any of the variables change.

The minimum safety distance is defined as the minimum distance from the light curtain's plane of light to the closest hazard or danger point where the operator could reach into the hazard. This minimum safety distance is based on the stopping ability of the machine and a hand speed constant.
