"One Perfect Part at a Time"

Thoughts on CAD/CAM/CNC

I am going to take a time out here from the product specific (BobCAD-CAM) examination I am making of a CAD/CAM software product.

I consider myself a competent self taught hobbyist CNC machinist. I didn’t get here without a lot of study and hands on practical experience. Let me say I have paid for my mistakes as well as my successes. The creative process of following through from an idea, to a sketch, Computer Aided Design (2D & 3D drafting), Computer Aided Manufacturing, (generation of Computer Numeric Control code), Controller (MACH3) set up and finally understanding the physical limitations of… Continue reading

Letting the Cat Out of the CAD

BobCAD LogoI am taking an opportunity in my project schedule to try another CAD/CAM package. I had looked at it long ago and it has been around for over 25 years. When I first saw it (back then) I believed it was one of those,”yet another CAD/CAM packages.” I am sure at some point I registered and ran at least the demo, as it seems I have been receiving occasional marketing from them forever. Back in that time, I was looking for a cheap all in one CNC solution. I was still a bit naive of all the requirements. I did… Continue reading

A View on CAD, CAM, CNC Software Upgrades

The Vectric (software) company has just released version 3 of their Aspire CNC software. Nothing too earth shattering as far as major changes that I can see, but some very nice-to-have upgrades in performance and design ease. The update from version 2 is $400.00 USD. Hmmm… a lot?

A new outright full edition Aspire purchase is $1995.00 USD. It is Vectric’s highest priced do-it-all CNC package. So the $400 update cost doesn’t sound too bad. I also got to thinking that a single skilled programmer writing updates and improvements just for me would probably bill out at over $100… Continue reading

CNC Gun Part

A local person here in Frisco asked if I could duplicate this part (the black one). I don’t usually like to take on outside projects as I have enough of my own. This part looked interesting. It is part of a tripod bracket for an expensive, but what the owner called a “toy” gun. Actually is is a very sophisticated collector item.

As can be seen in the photo the bracket had the tab broken off. It is a very nice injection molded aluminum casting but the crystallization left it vulnerable to breaking where it did.

I… Continue reading
