CNCUtil - CNC Library

The XDOBS CNCUtil Library allows Machinests to retain the control of the milling machine where it is needed while allowing the computer to do the hard work of producing the GCODE needed for things like circular pockets, Arc pockets, etc. CNCUtil also does most of the math which tends to take up a lot of a GCODE programmer’s time.

We have spent a considerable amount of time and energy getting up to speed for small scale production using CNC.

In this white paper we share a lot of the knowledge we gained through intensive study and a lot of trial and error. We hope it will save you hundreds of hours while also saving you thousands and up to hundreds of thousands of dollars.

We make this information freely available along with our CNC library because we figure that if you start using our CNC Library that you will need enhancements and we can provide those enhacements at a reasonable cost.

Reference & Background

• Overview Why we found it necessary to build the CNCUtil library and why we think you may find it beneficial. Includes Extensive links section for dominant CAD, CAM and CNC vendors.
• CNCUtil - users guide - An introduction in how to use CNCUtil our scripting library to generate sophisticated gcode
• Running the programs A document that explains how to use the DOS or Linux command prompt to run these samples and your own machining scripts how to save the output to be processed by your CAM driver like EMC2.
  
• Introduction to GCODE for Scripting Programmers. Includes links to several other tutorials and GCODE reference manuals.
  
• Library Class, Method, Attribute documentation Automatically generated from class and method defenitions and comments embedded in the source code. Once you understand the basics of using the system this is quite valuable.
  
• CNC Links CNC, CAD, CAM, Driver, STL, DXF, IGES links to vendors and standords.
  
• Ruby Notes A set of notes about ruby made while we where using Ruby to build CNC Util.

• • - List of Mini milling machine sites . Little machine shop also has a great learning section with bit speeds and other essential information. They also stock all those odds and ends that you need but can not find.
• • Tips for the Taig Mill mostly CNC related. Lots of good tidbits. Also incudes Nick Carter's Taig Lathe and Milling Machine Pages contains one of the best sites on the internet with the most comprehensive set of links. Nick is a dealer for the Taig mills and it is probably worth buying from him rather than futzing around on the internet.
