5.4 Simple arc processing
When processing moulds, it is often required to process arcs. In case
the shape is simple and the production quantity is very small, resources may
be wasted if a numerically-controlled machine tool is used. The function of
simple arc processing is provided at the display so that a single work piece
such as a copper pole of a mould can be conveniently and quickly processed
at a general milling machine.
With the control parameter
“
MAX CUT
”
, make
the arc to be cut every time equal. Control the smoothness of the arc.
When
MAX CUT is smaller, the cutting volume each time is smaller, and the arc to
be processed is smoother, the processing time is longer; when the MAX
CUT is larger, the cutting volume each time is larger, and the arc to be
processed is rougher, the processing time is shorter.
A: Processing ZX and YZ planes
There are 8 processing methods as shown in the following figure when
arcs on ZX and YZ planes are processed.
Note: A flat-bottom milling cutter or an arc milling cutter can be used
for processing. When a flat-bottom milling cutter is used for processing the
arc, set the diameter of the cutter to be 0.000.
B: Processing the XY plane
When processing the XY plane, there are also the preceding eight
processing methods. The cutter is vertical to the plane to be processed. Each
method is further divided into inner arc processing and outer arc processing.
Therefore, when processing the XY plane, select the cutter compensation
mode: processing of outer arc (1: T+T00L) and processing of inner arc (0:
T-T00L).
Note: When processing the XY plane, no matter round-head cutter or
flat-head cutter, set the radius of the cutter according to the actual value.
