# surface speed to rpm formula

### metric spaces

on a flat surface without any obstacle I need to calculate the Distance meters it would travel if i make the wheels to rotate for 4 seconds I can do that by Speed = Distance/time formula but for that I would require the Speed of the wheels I do not know the formula for Speed velocity calc with RPM and Diameter of the wheels.

### SFPM vs

06 02 2016  The above calculations given by others are all correct There is no rule for optimum rpm or surface footage There are calculations for things like speed ratios surface speed of wheel to surface speed of workpiece equivalent chip thickness Aggressiveness and maximum chip thickness But then again those are relative also.

### Disk Transfer Rate Formula

To reach our desired surface we have to cross 16 surfaces Total number of sectors that are crossed in 16 surfaces = Number of surfaces x Number of tracks per surface x Number of sectors per track = 16 x 1 x 63 = 1008 Now after crossing 16 surfaces surface 0 to surface 15 in cylinder 400 we are at surface 16 Step 03

### Speeds And Feeds For Milling With End Mills

Now choose the right surface feet per minute SFM or surface meters per minute SMM Use the SFM and the diameter of the mill to calculate the RPM of your machine Use the RPM IPT CLF and the number of flutes to calculate the feed rate or IPM If you want to be conservative choose a slightly lower SFM but always choose the recommended FPT.
