Learn Cnc Speeds & Feeds - with rpm & feedrate calculator

Feeds and speeds formula. First is the formula to find the RPM, RPM = SFM* X 3.82 / diameter of the tool (* SFM = Surface Feet per Minute) You can also use the RPM calculator below. Next, the formula for the feedrate uses the RPM from the previous calculation, Feedrate = RPM X Feed per tooth X Number of teeth. or.

Estimation of Machining Sustainability Using Fuzzy Rule

Hole-making is required in a plate of plain carbon steel (hardness = 25 HRc) using a carbide (uncoated) drill bit of 8 mm diameter under the lubrication effects of MQL (minimum quantity of lubrication). The two cutting parameters are fixed as follows: cutting speed = 100 m/min and feed rate = 0.1 mm/rev.
