Re: V Grove Fold joint

waw this looks great. two questions 1-on your final product you show recessed panel on each side, why you do not cut the middle part at the same time since you have tool changer cnc. 2-do you lay out all operations manually? is there any software you design box and software grove joints by generati...

Re: V Grove Fold joint

Here is an example in 1/2" LDF. Took about 3 sheets, so you won't see all the parts on this one sheet.

Re: V Grove Fold joint

I've done many folding mitres in MDF using a 91 degree V-bit. If I'm making a complete box, I just draw a line between each part and cut on the line. You need a pretty large bit to cut 3/4" MDF. The one I use has a 3/4" shank and is 1.5" diameter. I cut at 12000rpm and 200ipm in a single pass for th...

Re: Maloof style seat tutorial

The seat model is just a very generic shape and size, not really meant to fit any chair in particular. You can either resize it to fit your needs, or use the tutorial to create your own size of seat!

Re: Maloof style seat tutorial

Now you need to subtract a round over for the front edge. I draw some vectors as shown. seat 8.png Then do a two rail sweep, subtracting the sweep from the baked model. seat 9.png This gives a nice shape to the front of the seat. seat 10.png Bake the models, and then use the cutting tool as shown to...

Maloof style seat tutorial

I've been getting a few questions lately about designing a Maloof style seat in Aspire. I had a couple threads years ago, but they didn't go into enough detail so I thought I'd start a detailed thread showing my process in designing a seat. I'll include the file I end up with, so you can play around...

Re: Faceshield design if anyone wants.

Face shields should be used by all health care providers now. The corona virus is transmitted from large respiratory droplets (droplets that gravity will pull to the ground within 2m of leaving the mouth or nose). Masks are useful to protect against these droplets, but once a mask is exposed to drop...

Re: Any 5' x 5' CNC machines out there?

Let me just throw this out there. A 5x8 machine would be the same price (or very nearly, since its not custom) and if you buy a 5x5 it won't be long until you REALLY wish you had a 5x8!!! Fine for cutting 5xx5 sheets, but its no fun cutting down 4x8 sheets to fit on your machine!

Re: An Alternative 3D Finish Cut Strategy?

I would love to see some improvements on the finish toolpath! Another thing I'd like to see is to vary the stepover on vertical surfaces (like the option on the moulding toolpath). This would give far superior finish on more vertical surfaces. I'm not sure this is possible using voxels though, which...

Re: Roughing Vs Finishing toolpath

'Reasonable time' for 3D work totally depends on your machine. I would never consider doing a roughing pass on something like that. I'd use a raster cut at 18000rpm and feed speed of 800XYZ. Probably 45 minutes on my machine (its the acceleration/decelleration settings that makes the biggest differe...

Re: Z move when pocketing

Pocketing in V-carve is generally not very efficient. But it's easy, so sometimes its worth using that tool path. If I am setting up a file that will be repeated many times, I find it much more useful to use a profile cut. I just draw the lines exactly where I want my tool to cut (the offset tool wi...

Re: How to set Z height when prompted to ATC for clearence

You will need to change your post processor a little so it goes to the correct position and height when it needs the tools changed. Sounds like you have an ATC spindle. If I were you, I'd position all those extra cones you have onto a tool rack somewhere on your machine, and set up some tool change ...

Re: How to set Z height when prompted to ATC for clearence

With an ATC (automatic tool changer) you don't have to manually change tools, and you don't have to set Z0 when a tool is automatically changed. You set Z0 once (usually you just leave it permanently at the spoilboard, and never have to set Z0), and run the whole program without doing anything. Soun...

Re: Microsoft ends support for Windows 7

I have never updated the computer running WinCNC on my Cobra, and its windows 7 from 2011. Its also not connected to the internet. Still runs like a dream. I'm not concerned about the end of support.
