n = Spindle rpm
V = Peripheral speed m/sec
D = Diameter mm

EXAMPLE 1:
Determining the correct sawblade
diameter to cut melamine-coated
chipboard with a rpm of 4500 and a
peripheral speed of 70m/sec. The
correct blade diameter is 300mm.

EXAMPLE 2:
Determining the correct machine rpm
in order to cut at a peripheral speed
of 100m/sec with a 350mm diameter
sawblade. The correct rpm is 5500.

n (rpm)
EXAMPLE 1:
Determining the Correct Feed Rate:
Solid wood - chip size 0.15
Spindle rpm - 6000
Number of teeth - 36
You should use a feed rate of - 32m/min
EXAMPLE 2:
Determining Number of Teeth
Chipboard - chip size 0.24
Spindle rpm - 4500
Feed rate - 22m/min
Therefore the number of teeth = 24
