GCode is Complicated
G-Wizard Makes it Easy

Lathe Conversational CNC Kicked Off in G-Wizard Editor version v1.88

Apr 8, 2015   //   by Bob Warfield   //   Beginner, Blog, GCode, Software, Techniques  //  No Comments

Conversational CNC is a very popular feature among G-Wizard Editor users, but what is Conversational CNC?

Simply put, it is the ability to quickly and easily generate g-code by answering a series of questions rather than by producing a CAD drawing and then applying CAM software to it.  Conversational CNC is not really a replacement for CAM.  Rather, it’s an opportunity to keep simple things simple by not requiring CAM for simple projects.  For example, suppose you need to create a simple bracket that simple requires milling a rectangular piece of material and adding some holes.  A manual machinist would be done with that part before most CNC’ers would be done creating a CAD drawing and using CAM to generate the g-code, let alone making the part.  But, with Conversational CNC, you can operate quickly and shoot from the hip just as on a manual machine.  This is perfect for simple parts where CADCAM is overkill.

G-Wizard Editor already has a great many Conversational CNC Wizards for Mills, but we’re just getting started for Lathes.  This week, GW Editor version 1.88 was uploaded and it includes the Conversational CNC Facing Wizard for lathes.  The Facing Wizard looks like this:

The Conversational CNC Facing Wizard:  Simple G-Code creation without CADCAM…

As promised, it’s very simple.  There are some common choices along the top that all the Lathe Wizards share:

–  Work Offset:  Choose one of the work offsets for this program snippet.

–  Rapid to X and Z:  Rapid until you’re close to the point where cutting should start.  Motions that are closer than this XZ point are done at feed speeds.

–  Roughing and Finish Tools

–  Coolant

Next, there is a graphical depiction of the geometry of the Facing operation.  You’ll need to select Start and End positions in X and Z axes.  For example, to face a 3″ diameter workpiece with a 1″ center bore, enter X Start of 3 and X End of 1.  Facing might run from Z Start = 0.0 to Z End = -0.2.  That’s all the geometry that’s needed.

The remaining information specifies the Feeds and Speeds.  If you don’t know what values to use, you’ll find our G-Wizard Calculator cranks out Lathe Feeds and Speeds very nicely.

Here’s a quick video showing the Facing Wizard in action:

That video is from our G-Wizard University series, which are quick tutorial videos on each feature of our CNC software.  You can find them on the Help page, which is accessed by clicking “Help” at the top of any CNCCookbook page.

While we’re on the topic, I also uploaded a quick G-Wizard University Video that demonstrates the Debugger/Simulator in our G-Wizard Editor:

There’ll be many more Conversational CNC Wizards to come.  My goal is to get a new one out every other week until they’re all complete, so stay tuned!
