After using our CNC machine for more than eight years, we still find ways to be more efficient. One area we were looking at was bed cleaning after sheet processing. It was a chore to vacuum the bed with a shop vac after removing the processed pieces from the bed to ready it for the next sheet. 

I noticed a supplier selling a hose and wand system that integrated into an existing dust collection system and installed it thinking that it would eliminate emptying the shop vac. It did that and also reduced the clutter around the machine. This was a better way.

Then, while attempting to resurface the spoilboard one day, I forgot to reset the depth of cut. As the fly cutter flew across the bed at a depth of 0, I noticed that the dust hood was just touching the spoilboard and was sucking out the dust.

That's when I realized that I could program a spoilboard program that would swipe the board at the width of the dust hood instead of the cutter width. After storing the program in an easily accessible area, it now takes less than 60 seconds to vacuum the spoilboard and have it ready for the next sheet. No dumping a shop vac or swinging a heavy vacuum hose and wand in the process.

When I mentioned this tip on the Cabinet Makers Association (CMA) online forum, I got this response from Randy Nightengale:
 
“Good tip, Tracy. I also do that, but the guy who built my machine told me it could get dust in the collet. So I programmed the spindle to run at 500 rpm to help keep dust from sticking inside the spindle taper. I found out 500 is as slow as it will turn. Been doing it for couple of years now with no noticeable problems.”
