Video of CNC machining a double sided part.

[Shinobiwan]

This was a cool challenge not least because there was over £300 worth of stock material at risk if I nobbed it up!

A couple of days worth of planning, many iterations of tool paths and simulations and a day spent building and testing the double sided jig. This made a really nice change of pace from the usually slap a sheet of 4x4ft on the bed and press go. I've only had practical hands on experience with the cnc for the past few weeks and only done a handful of jobs so at time I thought I'd bitten off more than I could chew with this but it came good in the end. The two sides lined up virtually perfect and I couldn't be happier with the results. I learnt a lot from this, not least that long cutters (105mm from the collet) are whole other ball game and first hand experience of the superiority of carbide vs hss when cutting highly abrasive materials as well as the folly of using too many flutes and incorrect chip load. Burned two cutters up because of that just on this one job.

I'll post some of the pics later but for now here's a video:
