R Function - For 3 Axes Es-12; Three Axes Arc Machining Mode Operation - Easson ES-12 Operation Manuals

If 2 axes ES-12 is used, please skip this page and go to the next two pages to continue the R parameters entry.
For 3 axes ES-12, all the ARC parameter have been completely entered into the ES-12, the ES-12 will entered into the
three axes ARC machining mode as per follows.

Three Axes ARC machining mode operation :

In the three axes ARC machining operation, the DRO will calculate the ARC profile according to the current Z
axis position, and perset the X axis ( in case XZ plane R ) or Y axis ( in case of YZ plane R ) to 0.000 to guide the
operator to machine the ARC profile.
The operator can make Z axis increment to machine the ARC according to the surface finish they required.

R function - For 3 Axes ES-12

In this example, XZ plane R is selected,
therefore, move the X axis until X display = 0.000
then the tool is posited on the ARC curve.
The display will shift left to signify
it is not a normal coordinate display
In case the opeartor posit
the Z axis outside the R
curvature, the DRO will display
" r OU LI " - [ R Outside Z Limits ]
in the Z axis display
- 46 -
Since the X axis is preset
automatically with the Z
movement, therefore, we
call it AUTO R - XZ plane
