Apr 30, 2012   //   by Bob Warfield   //   Blog, GCode  //  No Comments

Those of you who are beta testing our G-Wizard Editor, be sure to upgrade to the latest 0.437 release.  I have fixed a crash/lock-up bug that could very commonly strike while editing code.  Thanks to our user Don for finding a set of steps that would reproduce this problem every time.  Once I had that…

How Much Torque on a Kurt Vise?

Apr 29, 2012   //   by Bob Warfield   //   Blog, Techniques  //  2 Comments

Found a good little tip over on CNCZone. One fellow says he put a torque wrench on his Kurt vise and discovered the fixed jaw starts to move if you torque it more than 45 ft lbs. Obviously you’re also asking for trouble if you crank your vise down with a workpiece only sticking partially…

A Couple of Very Cool 4th Axis Videos

Apr 28, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  1 Comment

I’ve been watching and corresponding with this fellow for a little while now, and he has just released two new videos:

Being able to lock the axis opens up some possibilities, like slotting keyways. I’ve been thinking about this possibility for a while, though not in conjunction with a 4th axis…

I noticed we were getting a lot of traffic to the Mill Tips and Techniques page from people searching for how to Tram their Mill.   So, I made a special page just about Tramming a Mill, added even more content to it, and put a few new things onto Mill Tips and Techniques since I…

New G-Code Course Chapter: Tool Changes and Tool Offsets

Apr 19, 2012   //   by Bob Warfield   //   Beginner, Blog, GCode, Software  //  No Comments

These new G-Code Course chapters come fast and furious when I am working on the G-Wizard G-Code Editor/Simulator and the addition of a new feature prompts me to write about it.
This chapter is called “Tool Changes and Tool Offsets” and describes how to go about programming tool changes in g-code on lathes and mills,…

New G-Code Course Chapter: G96 Constant Surface Speed Programming

Apr 15, 2012   //   by Bob Warfield   //   Blog, GCode, Techniques  //  No Comments

If you’re familiar with feeds and speeds, or if you’ve ever read through a tooling catalog, surface speed is a quantity used to define how fast the tool tip can move across the workpiece. It is handier than spindle rpm because it is independent of diameter. For a given rpm, surface speed changes at every…

Radio Controlled Submarines: What Else on a Friday the 13th?

Apr 13, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  No Comments

I was casting about for something kind of fun to post about this Friday the 13th and serendipity struck.  I went first to a classified for a CNC Router, which happened to be on a forum for submarine builders called “Sub Pirates”.  It didn’t take me long to wonder what sort of place I had…

How About Building a Scale Tank You Can Ride Around In?

Apr 13, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  No Comments

Continuing our Friday the 13th fun theme, I had also come across these nearly full scale tanks various folks are building some time ago.  My favorite was this series from an Aussie.  I must say, I’ve never met an Aussie who didn’t know how to have a good time, and this chap is no exception.…

Apr 6, 2012   //   by Bob Warfield   //   Beginner, Blog, CNC Router, FeedsSpeeds, Software, Techniques  //  11 Comments

While you can use endmills and twist drills that are typical of the non-router (routers are also called gantry mills, if you prefer) CNC world, there are a number of special cutters than can help out in a variety of situations and that’s what this article is all about.  For more on regular milling cutters…
