Understanding the Co-ordinate System :
For those operator who do not have experience in CNC programming, or the first time user of RD-11M's
R functions, they may find that it is difficult to understand what is meant by "co-ordinate".
The co-ordinate is a pair of numbers which specify a position on a surface.
When using RD-11M's R function, it is necessary to enter the co-ordinates of ARC center, start point, end
point and etc. to let RD-11M know the geometry of the ARC to be machined.
During installation, the engineer will set the display direction same the the dial of the
machine. For a Taiwanese made knee-type machine, because of the lead screw dial direction,
the RD-11M display directions are also be normally set as follows
.
Co-ordinate is a pair of number which specify the distance from the datum point ( zero position ), the number
can be either be positive or negative and depends on the direction relative to the zero position

B : Coordinate (+50, -20)
A : Coordinate (+30, -40)
datum point
(zero position)
0, 0 ( )
Example 2 :
please notice that the Y coordinate
is negative because it located at
the negative direction from the
zero position.
