When I surfaced the bed this morning (pocketing at 7000mm/min, 6mm 2 flute coated carbide bit at 0.4mm stepover and 0.5mmdepth of cut) I couldn't notice any ridge at all, totally smooth.....jammy bugger, makes up for the broken tap in the base!
    Why such a small step over neil.? . . . . With 0.4mm it must have took for ever.?

    The Acid test for tram is when you use a wide cutter.!! Try 50mm with 75% step over and see what happens.? 6mm with only 0.4mm step over will hide most error. Also cut both X & Y direction.
