While we’re waiting for the cases to be cast and heat treated, I’ve started to write some GCODE for fly cutting the mating faces. With such large components travel on the Y axis is very close to the limits, so a trial run over a set of drawings is a must!
The position of the spindle centre is also critical, and this afternoon I brought it forward. I hadn’t done this before but it was fairly straightforward and with Bob’s assistance now in the right place. Bob remains unconvinced that CNC is better than handle twiddling!
I think we’re going to be ok without resorting to larger machines. Great news as it is VERY close to the limit!
