· Whether you are programming a 5axis CNC machine or turning handles on a 60 year old knee mill the numbers don't lie. However, one very important lesson I have learned is to respect the variables. Any common formula you are going to use in the machine shop will provide you with the information you need to approach the cut appropriately but remember to always treat that number as .

Each calculated point is then plotted. The resulting curve is a parabolic curve as shown in Graph 1. The maximum mechanical power occurs at approximately onehalf of the stall torque. The speed at this point is approximately onehalf of the noload speed. Construct a table of the motor efficiency at various points from noload to stall torque.

Calculated Required Power. F t Tangential cutting force: lb N. T Torque at the cutter: Nm in.lb ftlb Nmm. Machining Power. P s at the cutter: (HPc) KW. P m at the motor: hp KW. These calculations are based upon theoretical values and are only intended for planning purposes. Actual results will vary. No responsibility from Kennametal is assumed.
Note: This equation is quite aggressive and in common practice it is often divided by 2. As an example let us assume that we have two 12in. diameter rolls, and we find that the nip widths are on the ends and at the center under the loading at which we desire to run the rolls. Then by our formula.

· Speed Formula. Milling machine cutting speeds are derived from the following formula: Figure 14 : Speed Formula. Speed is the rotational frequency of the tool (Spindle Speed) in revolutions per minute (RPM). SFM (Surface Feet per Minute) is the speed at which the material moves past the cutting edge (outside diameter) of the tool in feet per minute.
· Feed rate for milling is usually expressed in inches per minute (ipm) and calculated using: ipm = rpm × no. of flutes × chip load. What is chip load? When milling, it is the amount of material that the cutting edge removes each time it rotates. When turning, it is the distance the part moves in one revolution while engaged with the tool.
milling efficiency [26 28]. For mill speed, impact load increases with mill rotation speed, but higher speeds result in the wearing of lifters and increased energy consumption. For mill filling, a minor filling level results in economic cost increases, and an excessive filling .
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, Added Table Travel = Approach Length + OverRun. Length of Cut = Length of job + Added Table Travel. Feed/Rev. = Feed/tooth x Number of Teeths on Cutter.

Calculating feed rate: Unlike linear milling appliions (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:
Lower roller driven power is: In the above formula: P – Driven power (m • KW) T – Driven force moment (KN • m) n 2 – Lower roller rotation speed (r • min 1 ), n 2 =2 V /d 2 (V is rolling speed) η – transmission efficiency, η= The power of the main motor can be obtained from the value of P.
