below was last weekends mission repairing an antique chair for my father in law. i used an app, reality scan, to to create a 3d model of a similar intact pair of cherubs and then scaled it to hopefully fit the gap. about 8 hours of machining in oak.

does your machine have the ability to adjust the feed during the cut? 19mm bit, 12mm step over at 1mm deep sounds fine. id be tempted to speed up the rpm say 10000 and start at 500mm/min although i reckon this would be a bit slow and infuriating to watch. if you can manually overide the feed up...

interesting that might just do it , thanks

i whipped up a quick catch all type bowl on my cnc with a little silver inlay . anyone have any tips for trimming the silver wire without deformign the cut ends? bottom left of the bowl shows the jopin in the silver looking a bti scruffy..

Yes there will be a more appropriate toolpath like bore or something more suited to holes. I'm not Infront of a pc at the moment to advise definite terminology but try a different type of tool path.

Looks weird, I'd guess theres an issue with the geometry selected for the hole. What tool path strategy did you choose?

somethings not quite right there. face operations should remove all of the top face of your stock. i reckon you have a geometry selected that you shouldnt for that toolpath. leaving it there potentially presents material to your next toolpath that it isnt expecting to be there. if its cutting...

Okay this is where your model and stock become two different things. Is your current stock too thick and you need to get it to your model height? Use a facing tool path. You could use a pocketing tool path but your machine/ fusion need to know where to pocket to. Even typing this makes me...

Hmm I see what you mean. How wide is channel? Have you tried trace tool path with an axis offset to get the depth? I would definitely explore using a tool the same width as the channel and turn off lead in and outs. I solely use fusion , it makes me think I'm better than I actually am. I'm...

Run that past me again? Like machining a grid?

When you created the tool path the second tab will allow you to guide where the tool goes.as Mr Delaney said, the circle you drew for the top of your model should be able to be selected and then set the tool to machine inside that circle. It will then ignore that top face. Fusion is an...

i normally run with 15 - 20 percent. the drop in material removal can be countered by using the both ways option in the tool path set up page. this will use both both climb and conventional and stops the tool retracting between moves, saves a bit of time. what is it that youre making? just being...

yes so 7mm in the z and 2.8mm in its horizontal moves. 2.8mm is hefty , okay in a softwood, you might need to dial that down in anything harder. looks pretty good apart from the tear out on top, either get yourself a compression bit or run a second op with a downcut bit. with a compression bit...

i always run with climb

yep stock to leave will be it, axial leaves 0.5mm in the z and radial leaves 0.5mm in the y and x. adaptive toolpath is good for 7mm deep no problem and thats a healthy optimal load. easy..

and have you managed to model , simulate that in fusion?

im amazed that anyone could make that table without a cnc, very good.....

i have a relativley small desktop cnc router, workable area of 750 x 750 ish, and im always surprised at how slow the sweet spot for my spindle is when running at an average of 2500 - 3000mm/min. i agree with mr sideways, 2 flute carbide cutters 4mm or 6mm with a spindle speed of 12000 rpm is...

thats good to hear. i dont have a tool change on mine but set up a limit switch sat vertically which i then run a probing macro to set tool height. whilst the changing of the bit is still manual, setting its length is about as close to automatic as it can be. im currently running through 17 oak...

steve im interested to see how you're getting on with your cnc machine? does it do what you hoped it would? chjeers
