( ALSTOM DCDM "SNAP-OUT" 10 segment - Front Panels - 180.9 x 45mm cut-out
( Set start reference datum at x3650, y4525 - offset from the 0:0 referenced datum corner
( Install 3mm Short series Slot Drill or FC3 End Mill
( set cutter depth to penetrate 1.25~1.3mm deep on both sides
( the 1.25~1.3mm depthg leaves a middle-section of 0.4~0.5mm to "snap-out"
( the panel is turned over and the whole sequence repeated on reverse
( such that the segments may be snapped out according to customers needs
( 1st pass is made with the 1st roughing pass 0.2mm smaller
( 2nd pass produces the 'snap-out' segmentation
( 3rd pass 0.2mm bigger for finishing the outer main opening
( final size and the 2nd pass finishing to the final size
( the travel concludes when the 3rd pass reaches x=0.00; y=0.00
( Spindle speed set to 3000rpm
( operation begins automatically when quill TDC switch is open
( raise the quill at the end of the X+13100mm stroke
( with appropriate care the part can be removed during the x-13100 stroke
( 80% Kero+ 20% RTD is used as cutting lubricant during the X+13100mm cutting stroke
( return speed may be increased if justified by higher production rate
