So, to solve for chip load per tooth, you could rearrange the formula to look like this: IPM / RPM / Number of Flutes = CLPT. See, not too bad. All of this math is essential to succeeding as a machinist. Knowing these conversion tricks and formulas by heart could save you minutes or more in a job process. Common Drilling Formulas RPM RPM = vc x 12 3.14 x D or RPM = (3.8197 / D) x SFM (rev/minute) Cutting Speed vc = RPM x 3.14 x D 12 or SFM = 0.2618 x D x RPM (ft/min) Feed Rate vf = IPR x RPM (inch/min) Cross-section area of hole AT = 3.14 x R2 (in2) Material Removal Rate Q = vf x AT (inch3/min) Power Requirement Pc = D/4 x f x vc x kc 33,000 x ... Determination of Mathematical Formulae ... 75 without any cutting ﬂuid (DM – Dry Machining). The collected data was used to determine a mathematical calculation in the form of power polynomials that enabled the calculation of the cutting forces, Fc. The test stand for the measurement of the forces consisted of a Haas SL10 CNC turning lathe ...
