Optimising bar remnant
By observing the following recommendations, it is possible to reduce bar remnants to make
best use of the material.
C
Precisely adjust bar end
C
Machine close to the chuck (clamping device)
C
Calculate optimum bar length
Calculating optimum bar length
A
:
maximum bar length
a
:
length of workpiece feed
b
:
minimum clamping length
l
:
optimum bar length
L
:
initial bar stock length
W
:
number of workpieces that can be cut from a bar
Example :
A bar of length 3100 mm (122") is to be cut in order to be loaded by ECO
LOAD. The feed length per part (part + face tr tool width) is 80
mm (3.15"). The minimum chuck clamping length (chuck
projecting part) is 40 mm (1.57").
A = 1200 mm (47.2")
W = (A-b) /a
L = 3100 mm (122")
W = (1200 mm - 40 mm) / 80 mm ; (47,2" - 1.57") / 3.15"
a = 80 mm (3.15")
W = 14.5
b = 40 mm (1.57")
we opted for : 14 pieces per bar
W x a + b = A
l = W x a + b
W x a = A - b
l = 14 x 80 mm (3.15") + 40 mm (1.57")
l = 1160 mm (45.7")
W = (A-b) / a
The bar of initial length 3100 mm (122") has to be cut as follows:
Two lengths of 1160 (45.7") will leave bar remnants of 40 mm (1.57") and a third length of
780 mm (30.7") will leave a 60 mm (2.36") bar remnant.
The waste from the original bar stock is the total of the 3 bar remnants, which is 140 mm
(5.5").
