Re: Does it matter what side of the 4th axis that you cut on?

I replaced my 4th axis with a lathe and I always cut from the side with a 1/2" downcut endmill. I turn the lathe at 300rpm and have it turning up into my cutter (so the downcut edge sheers the wood like a regular knife would). I spin the end mill at 18000rpm and usually have a feed speed of 10ipm. I...

Dough bowl and a pencil plane holder

Worked on a couple projects this weekend. The first is a wood bowl for proofing dough for french bread. I had a glass lid already, so I needed a bowl that fit that lid (so I could monitor the dough). Used the molding toolpath for both sides (love that toolpath). The second project was a curly maple ...

Re: Shaping around an inside profile cut

The quickest would be a round over bit. You can buy them without bearings, in many different radiuses.

The second best option would be to use the moulding toolpath for each hole. This is so much better and quicker than a finish toolpath.

Re: limitations of moulding paths

I still think the moulding tool path will give you better results than using a 3D toolpath, even though you do get some waste cutting. The way a moulding tool path is calculated gives much better results than the way a 3D tool path is calculated in Vectric products.

Re: Ya! or Na !

Wow. I would suggest if the updates annoy you that much, then simply do not update your software. You certainly don't have to, if the version you have does what you need. Personally, I love the updates. Sometimes I'll skip one, if I'm not in the mood to upgrade. But there are some 'must have' update...

Re: V-Carve small text for inlay

Why do you think that is too shallow to inlay? The smallest letters in this example are just 0.2" tall. They turned out fine. I used a 60 degree V-bit.

Re: Two-sided model question

Or just set your Z0 1/4" higher than normal (on your machine, not in the file), and that will give you a 1/4" extra between the two models when you flip the piece.

Re: How to maintain the ability to measure Z zero

Most machines with limit switches will save the offset of your tool, and when you turn your machine back on and 'home' it (by touching off on the limit switches) it will 'remember' your XYZ zeros. For those that don't have this, always zero off the spoilboard. There are very few reasons not to do th...

Re: Offset rotary path

Just offset the centres by half an inch towards one side of the 2x2 (when placing the wood piece between the centres in your 4th axis). No need to make this a complex problem by trying to model it offset.

Re: Days like this make me hate my CNC

Just a heads up for the future - I ALWAYS check the tool path preview in the 3D window to see exactly where the cuts will be, and how deep they will be. You can rotate the workpiece around and see the blue cut lines and make sure they are cutting exactly where you think they should be. That also sho...

Re: New cnc.

Save up enough to buy a little cnc milling machine, or convert a milling machine to cnc. That would be far superior for cutting aluminum. Otherwise you will need to buy a very solid CNC router, and expect to spend around $10k.

Re: 3 axis mill/software business Idea

The longer I'm working with CNC routers, the MORE controls I want in my 'box'. I want servo motors with glass encoders and high end servo controllers. I want limit switches. I want control software that is easily to customize and write macros for tool changes, measuring and storing tool offsets, har...

Re: What do you do while the CNC is running?

I start sanding parts while other parts are cutting. Building furniture, the CNC cutting is the fastest part of the job usually. While one piece is cutting I'm either jointing and planing and gluing up the next blanks, or sanding the last parts to come off. I try to time my cuts so that they take ab...

Re: pizza oven mould

When we made a pizza oven we just cut foam as a solid model (not hollow inside) and packed clay around the foam to form the outside dome and door (the foam formed the inside shape, and we formed the outside freeform). Then we cut and removed the foam once the clay dried, and built a roaring fire ins...
