End mill tip radius? : r/Machinists - corner radius end mill

What is the cutting time required for finishing 100mm width and 300mm length surface of a cast iron (JIS FC200) block when the cutter diameter is ø200mm, the number of inserts is 16, the cutting speed is 125m/min, and feed per tooth is 0.25mm. (spindle speed is 200min-1）

What is the cutting time required for finishing 100mm width and 300mm length surface of a cast iron (JIS FC200) block when the cutter diameter is ø200mm, the number of inserts is 16, the cutting speed is 125m/min, and feed per tooth is 0.25mm. (spindle speed is 200min-1）

Substitute π=3.14, DC=125, n=350 into the formula. vc=(π•DC•n)÷1000=(3.14×125×350)÷1000 =137.4m/min The cutting speed is 137.4m/min.

vf(IPM): Table Feed per Min. z:Insert Number n(min-1): Main Axis Spindle Speed (Feed per Revolution f=zxfz) fz(IPT):Feed per Tooth

Calculate table feed per min vf=0.25×16×200=800mm/min Calculate total table feed length. L=300+200=500mm Substitute the above answers into the formula. Tc=500÷800=0.625(min) 0.625×60=37.5(sec). The answer is 37.5 sec.

What is the table feed when feed per tooth is 0.1mm/t., number of insert is 10, and main axis spindle speed is 500min-1?

vf(mm/min): Table Feed per Min. z:Insert Number n(min-1): Main Axis Spindle Speed (Feed per Revolution f=zxfz) fz(mm/t.):Feed per Tooth
