I must be greater than Tool Radius but less than K. I: Radis of the first circle (or finish if no K). The D-Word is modal, so if none is specified, the last value of D will be used. If you use D00, it tells the Haas not to use cutter compensation. Here are the words you'll use to create the pocket:ĭ*: Tool radius or diameter. G12 cuts in a clockwise direction while G13 cuts counter-clockwise. These special Haas g-codes make it easy to perform the operation. It's a case where an endmill is programmed to follow a circular or helical path to make a much bigger hole than the diameter of the endmill. Now let's go through and break down each one to see how it works.Ĭircular Interpolation or Helical Interpolation is something we see often in CNC programming. G53: Non-Modal Machine Coordinate System.What are the Haas Unique G-Codes for Mills? This article is all about picking up those things today, so let's get started. It also means that the vast cadre of folks who know Fanuc g-code programming are ready to be productive day one on Haas machines, and they can pick up the things Haas added as they need to. This is a smart strategy because it means most Fanuc g-code will just run on a Haas, yet they still have some great advantages to talk about due to the special codes they've added. They didn't make any arbitrary changes and they largely added good value and convenience. They started with the world's most popular dialect, Fanuc (what the bulk of this course is concerned with) and built on top of it while maintaining compatibility. Haas: Smart strategy when it comes to their CNC G-Code dialect. The good news is that Haas has taken one of the smartest approaches I can think of in creating their unique g-code dialect.

Haas makes some of the most popular CNC machines in the world, so knowing how to use their unique g-codes can be an important skill. Programming Haas CNC Machines: Haas's Unique G-Codes and Other Differences
