Calculate spindle speed in rpm from surface speed in feet/min by dividing surface speed by the cutter ( or work, on a lathe) diameter (in inches) divided by 4, or the other way round, 4 times sfm then divide by diameter (you're dividing sfm by the cutter circumference in feet, basically) - so your 1" diameter cutter would rotate at 600 rpm if you wanted 150 ft/min, a …

Problem 1 (25 pts): A grinding operation is taking place with a 15-in. grinding wheel at a spindle rotational speed of 5000 rpm. The workpiece feed rate is 100 ft/min, and the depth of cut is 0.0015 in. Contact thermometers record an approximate maximum temperature of 2100 ?F.

I think the wide RPM range of a spindle is a big advantage in most cases to optimize cuts with larger diameter tools. Whereas a high-speed router is a plus with the smaller diameter tools. I think the calculator can help make a good decision on your upgrade. As I always say play in simulation twice before making a cut once.

You can always ask your grinding wheel supplier for a calculator. I keep one in my desk and one in my toolbox. It is a quick and easy tool. Where you worked before you maybe had constant speed but you would have still had to input into the machine what SFPM you wanted to run at.

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

The dress speed ratio is the relationship between the dress roll velocity (V r ) in sfm or m/sec and the grinding wheel velocity (V s) in sfm or m/sec. and can be calculated using the following equation: Speed ratio = V r ÷ V s. The dress speed ratio can be a positive or a negative value as shown in Figure 5.

The Interaction of Surface Speed and Spindle RPM. Consider this table which shows tool diameter versus surface speed at 10,000 rpm: Surface Speed vs Diameter at 10,000 rpm… If we keep rpms constant, Surface Speed is directly proportional to diameter.

Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

SFM to RPM Calculator. Online speeds / feeds conversions calculator helps to convert SFM (Surface Feet per Minute) to RPM (Revolutions Per Minute) units.

This calculator will determine speeds and feed rates for machining operations on mill or lathes. Cutting speeds are usually given in feet or meters per minute and these speeds must be converted to spindle speeds, in revolutions per minute, to operate the machine.

First, calculate the cutting length per min. from the feed and spindle speed. I=f×n=.008×1000=8inch/min Substitute the answer above into the formulae. Tc=Im÷I=4÷8=0.5min 0.5x60=30(sec.)The answer is 30 sec.
