How can I reduce machining time on this project?

[VGCustomShop]

I would like to reduce the machining time on the pockets - the contour is fine.  Any suggestions are appreciated.

Try playing around with an adaptive clearing strategy.

The same feed rate with an 0.15" step down and a 0.15" optimal load will reduce your machining time by about 35%. I'd test those settings on some scrap before you go at the actual work piece though.

Maybe use a Planer bit or Rabbeting Flycutter for the larger center area?

Been working with your suggestion - getting a lot of yellow lines - is that OK?  Or is there a way to minimize that?

Thanks much for the suggestion!  The adaptive clearing - has cut time by about 80 minutes.

Glad it helped. I think the yellow lines are rapid traverses. I'm not sure of a way to get rid of that as the CAM engine just decided it was appropriate for some reason.

Awesome - getting ready to give it a whirl.  Just to check out the travel limits - as it turns out the machine shows more x travel at the back (17.56) versus the front (17.43) - the Y travel is the same on both sides at 17.8 - regardless the travel is further than expected.  I hope this doesn't mean I screwed up somewhere putting it together!

Fusion said that it would take about 1:28 to route - it ended up being 1:58 - is real world time often different from the Fusion estimates?  Seems the machine could run faster without causing issues.  The bit is only entering the wood one direction - seems it would shorten things by going both ways - could that cause problems? . . . have so much to learn.

Here's a short vid of the process - many thanks to Derek for giving me great advice on the CAM - BTW have given up on Picsender - updated it with the new release, thought maybe it was W10 but it doesn't work very well on the old laptop with XP either - stops at various places and claims there are problems with the grbl code.  Switched to the basic version of UGS and the entire hour and fifty eight minutes went without a hitch!  After this - glued the book matched ash top on and tomorrow will route the pickup, neck. control pockets and the f-hole.  Fun stuff.

Great work! Thanks for the video post.

Sweet video as always. Thanks for sharing.
