Formula of Feeding Rate per tooth

In this post I will concentrate on feed rate factors and calculations of saw blades. The Formula is :

Sz = 1000.F/N.Z
where F : Feeding speed (m/mm)
N : Number of Rotation (rpm)
Z : Tooth number of saw baldes


example : what SZ if cutting process is across grain?

F : 20 (m/mm)
N : 3600 (rpm)
Z : 40
we can use the formula
Sz = 1000.F/N.Z
Sz = 1000.20/3600.40
= 0.138

Recommend of SZ

1. Along Grain SZ is 0.8 mm/tooth
2. Across Grain SZ is 0.2 mm/tooth
3. Board SZ is 0.25 mm/tooth
