PCD - tool positioning for Pitch Circle Diameter
ES-12 provides the PCD function for tool positioning for the drilling of the pitch holes along a
Circle, operator simply enter the machining parameters as per the step by step guide that
shown on the DRO's message display, then the DRO will calculate all the pitch holes position
coordinate, and temporarily preset those holes' position to zero ( 0.000, 0.000 ).
Operator simply move the machine until the X,Y axes display = 0.000, 0.000,
then the Pitch Holes' position are reached.
Machining parameters :
- Centre ( CENTRE ) ......................... X=0.000, Y=0.000
- Diameter ( DIA ) ............................. 80.000 mm
- No. of holes ( NO. HOLE ) .............. 5 holes
- Start angle ( ST. ANG ) ................... 30 degree ( clockwise )
- End angle ( End ANG ) ................... 300 degree ( clockwise )
after the above machining parameters are entered into the
DRO, the PCD function will temporarily preset all Pitch Holes'
position = ( 0.000, 0.000 )
operator can press or keys to select the Pitch Holes,
and move the machine to
display = ( 0.000, 0.000 ), then
the Pitch Holes' position along a
circle is reached.
