Ball head of the milling cutter diameter Deff general than the calculated milling cutter diameter Dc, so the actual speed milling cutter diameter should not be calculated according to the Dc, and should press calculation Deff diameter calculation.

Deff = (Dc ²-(Dc-2 x ap) ²) 0.5

Dc for milling cutters, ap for cutting depth in diameter. But:

N = Vc x 1000 / (PI * Deff)

Formula:
3.14 * d * n
Cutting speed Vc =- - - - (m/s)
1000

Vc * 1000
Spindle speed n =- - - - -(r/m)
D * n

 

Feeding f = fz * Z (fz-each time feeding, Z-knife gear)

The speed Vf = n * * Z fz

Ball head Deff milling cutter
Milling cutter diameter Dc
Cutting depth ap

2 2
Deff = {Dc-(Dc-2 * ap)} * 0.5

 

Vc * 1000
N =- - - - - (mm/min)
P * Deff

 

Cutting width L: (also called step distance) step cutting width L and tool diameter d into
Direct proportion, and cutting depth is inversely proportional to the.

D = d-2 r (r fillet radius)

A knife: L = (0.6-0.9) d
Round nose knife: L = (0.8-0.9) d

Depending on the plane or cant knife of head of residual height control:
I 'QiuDao center and former after a QiuDao center distance'
R 'QiuDao radius'
H 'residual high'

...... (plane) I = 2 R * R-(h-R)......
(I ` = I cant) (library functions like sin @)
...... H ` = R-.....

UG programming essentials knowledge:

Contour cutting method is generally used for parts of the essence of wall or shape outline plus
Work, the shape thing closed or open, can be continuous or
Is not a continuous, specific application of wall and the processing, steep slope, appearance
