function : It is quite common to need to machine round a corner or an arc surface in the course of a day's work,
especially in mould making.
If the arc surfaces are complicated or a number of round corners have to be precisely
machined, or arc or round corners are to be machined, then CNC milling
machine should be used.
There are still a lot of the cases, however, that only a simple arc surface or one or two round
corners need to be machined and the precision of those arc or round corners machining are not
demanding ( especially in mould making ). If we do not have a CNC machine in house,
it is then more cost effective and time saving to carry out simple arc or round
corners machining on your manual milling machine in-house rather than sub-contract it as
CNC machining externally.
In the past, many mould makers made their tool positioning calculations for ARC machining
with a scientific calculator. But the process is time consuming and easily prone to mistakes.
RD-11M features has a very easy-to-use tool positioning function for ARC machining which enables
mould makers to machine simple ARC in the shortest possible time. But before you make your
decision to use the ARC function or to have your work piece to be machined in a CNC machine,
please bear in mind that ARC function is only cost effective and time saving under following
conditions
1) One off job
2) Only simple ARC surface or round corners to be machined.
.
In RD-11M, the ARC function group consists of two functions as follows
Simplified R function R function
R function provides maximum flexibility in ARC machining,
the ARC sector to be machined is defined by the
co-ordinates of :
1) ARC centre ; 2) ARC Radius ; 3) ARC start point
4) ARC end point
Advantage :
- Very flexible, R function can machine virtually all
kinds of ARC, even the intersected ARCs.
Limitation :
- Relatively complicated to operate, operator needs
to calculate and enter the co-ordinates of ARC centre,
start point and end point into RD-11M.
The RD-11M's ARC function is aimed at machining only simple ARC or
round corners, and to make the operation really very easy for the operator,
the RD-11M presets the eight type of most frequently-used ARC machining
processes.
Advantage :
- Very easy to use, operator doesn't need to calculate the
ARC parameters, just position the tool at the start point, and then
he can start the ARC machining immediately.
Limitation :
- Restricted to eight type of preset ARC only, cannot machine
more complicated ARC such as intersected ARCs.
