Smooth R Arc Calculation function (ARC Function)
In the processing of moulds, it often happens that the processing of circ
arc is indispensable. For the case that the processing
is
arranged for
a s·
working piece, the required contour
is
simple and not
too
much processing:
circular arc will be involved, it may involve much dissipation in both lime
mouey to an·ange the job to a digital control machine tool.
The advanced smooth R
arc
Calculation function provided in SDS6 mod
digital display box makes it possible to complete the processing of a single pi
such as moulding copper electrode easily and quickly with a universal mill!
machine. Th.is
arc Calculation function makes it possible to freely control
smoothness of the circular arc. The distance between two adjoining working po·
is uniform, the smoothness
of
the circular
arc
can be control through the control
o
this distance.
This function is used in the processing of circular arc. (l)Thc display on the
message window prompts the operator to enter all the parameters have to be
defined, so it is very easy to operate.
®This
function can based
on
the input
maximal cut (MAX CUT) calculates out the most proper depth of cut, and so, the
smoothness of the circular arc in thoroughly iu the operator's control.
1) An operator without
experience

understanding of·
the coordinate system in using the Arc R calculaliug function.
