In a piece of aluminum you want to make a pocket (milling of cavities), an end mill tool of 6 mm in diameter and 4 cutting sides will be used, the height of the cutting sides of the tool is 25 mm. The feed that will be taken per tooth will be 0.00003 meters / tooth, and a linear feed rate of 2.4 mm / second. Calculate the cutting speed in mts / min.

speed is 22.61 m/min

Explanation:

given data

diameter D = 6 mm

side z = 4

height h = 25 mm

feed f = 0.00003 meters / tooth = 0.03 mm / tooth

feed rate of 2.4 mm / second

to find out

cutting speed

solution

we will apply here speed formula that is

speed = π*D * N ... 1

so we find d first here by feed rate formula

feed rate = feed * z * N / 60

put here value

2.4 = 0.03 * 4 * N / 60

N = 1200 rpm

so from equation 1

speed = π*D * N

speed = π * 6 * 1200

speed = 22619.46 mm/min

so speed is 22.61 m/min
