Simplified R Function
In case 2 Axes ES-12 is used, we must first reset the Z Dial to simulate the initial Z position at the ARC's start point
**** Only for 2 Axes DRO, not valid if a 3 Axes DRO is used ***
** Posit the Tool at start point of the ARC to be machined **
Set the Z axis Dial
to ZERO ( 0.00 )
1. Select the work plane - XY, XZ or YZ plane R
2. Select the R type ( R type ) - Type 1 to 8
3 Input R's Radius ( R )
4. Enter to Tool Diameter
(
TOOL DIA )
Following parameters needed to enter into the DRO for simplified R machining
5. Machining STEP increments ( Only when for 2 axes ES-12 is used or machining the XY plane R )
Since in the 2 axes ES-12, there is no Z axis available, in order to make the machining of XZ and YZ plane R
possible, we need to simulate the Z axis position by mathematical method, also, we need to simulate the
Z up/down increments by the UP or DOWN key press so that the DRO can calculate the XZ / YZ arc machining
position accordingly, this parameter is to specify how the Z position increment when UP or DOWN key is pressed.
When machining the XZ and YZ plane R in 3 axes ES-12, no need to enter this Machining STEP increments,
it is because the DRO can calculate the X or Y machining positions and set those points to zero to guide the
operator to machine the ARC according to the current Z position. In case the Z position are out of the ARC's
Z position range, an warning message [ r. OU LI] - R is outside the Z limit is displaying on the Z axis of the ES-12.
For XY plane R, Max. distance
between interoplated points is
to be specified as the machining

For XZ/YZ plane R, the Z STEP parameter
is the Z step increments per UP or DOWN
key press. The Z increment distance is fixed
and specified by this
parameter.
For XZ/YZ plane R, if the R MODE parameter of SETUP
is selected to be MAX CUT, the DRO will calculate the
Z step increments per UP or DOWN key press so that
the Max. distances between each machining step
are approximately the same for a
smoother ARC machining.
