Two Axes Arc Machining Mode Operation - Easson ES-12 Operation Manuals

Two Axes ARC machining mode operation :

During the XZ and YZ plane R machining, it is necessary to accurately posit the Z axis to obtain a precise Z
position. However, there is no Z axis in two axis DRO. Therefore in order to guide the operator easily posit the
Z axis during the ARC machining. DRO use the unused axis display to display the Z dial turn number and Z dial
reading to guide the operator to posit the Z axis.
At the beginning of the ARC machining, the DRO will start and assume the Z axis dial at zero position with the
tool posited at the starting point of the ARC, then press UP or DOWN key once to simulate Z axis move up or
down the Z axis for one step, the corresponding Z dial turn number and Z dial reading will display on the
unused axis. Operator just need to move the Z axis according to the dial reading display on this axis, then
the correct Z axis height is reached.

Move the X axis until display = 0.000
then the tool is posited on the ARC curvature
