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.
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.
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
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.

23 09 2021 Most rotary devices are measured in revolutions per minute or rpm If someone told you your car s tire rotated at 1 000rpm that wouldn t mean much to you the speed of the car can t be explained simply by rpm because speed is
29 12 2020 Given the dimensions of your plate you could convert RPM into a speed and use this to calculate shear rate Your should therefore be
27 08 2001 To figure the speed the belt is moving you need to know the diameter of the contact wheel multiply that times pi to get the circumference of the wheel Then multiply that times the rpm of the motor That will give you inches

3 Decrease RPM until finish deteriorates then bring RPM back up until finish is acceptable 4 This optimizes RPM and speed to remove the largest possible chips To reduce the amount of work needed a range of feeds and speeds is provided to start at step 1 above To increase performance optimize feeds and speeds as detailed above.
