Dec 14, 2010   //   by   //   Blog, Cool, Techniques  //  No Comments

Kenneth Maxon, who runs the fascinating Max’s Little Robot Shop, wrote to tell me of some Starrett calipers he has which incorporate a precision spring loaded device for precise positioning. He describes it thusly:

A Caliper Pressure Device

Dec 14, 2010   //   by Bob Warfield   //   Blog, Products  //  4 Comments

Most machinists know that if you need accuracy to a thousandth (0.001″) or better, you can’t use a calipers. At the same time, the digital calipers is such a convenient tool for ID, OD, and length measurements. Machinist’s of yore were fond of their steel rule, but many of the newer generation are fond of…

Dec 10, 2010   //   by   //   Blog, Software  //  No Comments

We’ve always been able to properly calculate the tapping drill size for cut and forms taps, but now we’ve added feeds and speeds for carbide cut, carbide form, and HSS form taps. As you will see, these taps can bring a lot faster tapping performance to the table (pardon the pun!). G-Wizard will also tell…

Candy Red Powder Coating

I love the finish on aluminum IronMan from CNCZone is getting here:

Translucent Candy Red Powder Coat, not anodizing!
While it looks like a nice anodizing job, IronMan reports it is Columbia Coatings Translucent Candy Red. I have the impression from the post he chose it because he didn’t want to go to the trouble…

Special Purpose Robots

Dec 3, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool, Techniques  //  No Comments

We’ve reached a point where its actually pretty easy to build special purpose robots for various manufacturing tasks. For example, here is a robot that cuts off blocks of resistors from the rolls that feed pick and place machines. It’s used to put together parts packages for electronics kits (hat tip to MAKE Magazine for…

Heated Outdoor Furniture

Dec 3, 2010   //   by Bob Warfield   //   Blog, CNC Projects  //  No Comments

I’ve had this crazy idea for a long time, so bear with me as I explain it. I live in Northern California right on the Monterey Bay. The views are gorgeous and the weather is generally good, but it can get pretty chilly at night. It’s a shame, because the clearest most gorgeous nights are…

Dec 3, 2010   //   by   //   Blog, Software, Techniques  //  1 Comment

If you want to minimize tool marks resulting from lead-in and lead-out moves while profiling, align those moves with the part corner. For example, check out those moves on this part:

Finished part is blue, toolpath is yellow. Note lead-in/lead-out on the lower corner, exaggerated for emphasis…
The technique works because the tool only touches…
