Machining in the 4th Dimension

The fourth dimension is often mentioned in science fiction as a dimension beyond the human senses. Today, real scientists (if there are such people) claim the fourth dimension does exist. But there are IMHO plenty of pseudoscience, especially promoted as video “entertainment.”  Material for a future rant…

In machining there really IS a fourth dimension. Usually called the 4thaxis. The Hobbyist Machine Shop (THMS) has a fourth axis for use on the Taig micro mill. It’s been on both the mill used for metal machining as well as the wax milling machine. Currently it is on the Taig… Continue reading

DeskProto for 4th Axis

Using 4 axis milling, requires a CAM software system to create the necessary CNC G-code. It’s not something one can easily hand code when doing 3D designs. Simple level surfacing could be hand-coded on a 4thaxis, but probably lathe turning would be far easier.

Aspire, a three-dimensional CAD/CAM produced by Vectric can produce G-code for the 4thaxis. It is one of my go-to programs. However, I don’t design everything in Aspire CAD. Fusion 360 and RhinoCAD are also programs I use for design.

Both these programs have 4 axis CAM built in. Fusion 360 has a… Continue reading

S. Whiplash, Typical CAD

It’s been a while since I have run my original CNC Taig Micro-Mill. It’s the one configured for metal work and has the mist cooling installed. There is nothing operationally wrong with it as far as I know. Just haven’t had a project where I needed its services.

I have always used RhinoCAD (Rhinoceros) with RhinoCAM to generate the design and the Gcode necessary to run the mill. I am presently working with FUSION360 CAD with its built-in CAM. FUSION360 has become my go-to CAD for 3D printing because of the very good built-in… Continue reading

Autodesk Fusion 360

First look. I poked around looking at the trending in 3D CAD/CAM tools. Autodesk (AutoCAD) has always been at the top of my unobtainable list because of cost. I have a now quite old LT version which is strictly 2D. I also have a standard AutoCAD I think is version 4 or 6. Neither are installed on my machines. I need 3D.

In my web search I discovered a new tool from Autodesk called Fusion 360. I was actually reading about Apple’s new super powered iPad Pro. I thought if I owned an iPad Pro, it would have… Continue reading

Taig CNC Mill

Taig CNC Mill with 3D Parts.

I purchased a new 3D printer I have been using intensively for a few weeks. It is a low end hobbyist machine of what is called a RepRap design. You can read much more about it in Ramblin’ Dan’s Workshop. Here is a link to the section on 3D Printing.

What’s so cool is that now I am capable of both additive and subtractive creating. I have put the two together in an article, Taig Mill Swarf Blower, in the THMS main web site. The resulting combination is shown in the… Continue reading
