CNC Prototype Manufacturing
Firstly,
the technological characteristics of CNC machining center. Its characteristic
is that
it try to finish multiple operation such as milling,drilling, boring,
hinging, tapping in one clapping
as far as possible. It adapts large cutting
parameters.
aluminium alloy and copper.
Secondly, the notice when ensuring process program:
(1) Machining content of CNC machining center
should be confirmed. The installing cardinal
area, manching cardinal area and
machining allowance of workpiece also should be ensured.
Manufacturing
procedure should be arranged with the purpose of developing efficiency of
CNC
machining center.
procedures are difficult to finished at a time. The second and the more than one times of claping
can be
considerated.
(3) When manufacturing procedure, the principle
from roughness to precision should be followed.
Firstly, the working allowance
of heavy cut,rough machining and removing workblank should be
arranged. And
then the part without high procision should be arranged.
(4) The cooling method of large flows should be
adapted, which can reduce the mass heat affected
the machining accuracy. In
order to improve tool life, the cooling method of large flows should be
adapted
actively.
