It’s also an extra-cost option to enable rotation. Like scaling, rotation is also available in Fanuc, but it’s slightly different on Haas. That g-code will move the table to machine zero in Y. You must use it with G49 if you have a Z value as G49 cancels the tool offset. G53 lets you cancel the work coordinate system for one block. G53 G-Code: Non-Modal Machine Coordinate System Scaling is handy for a lot of purposes, and our chapter on scaling has more details on that. Note that scaling is an optional extra-cost feature on Haas controls. If there is no P specified, setting 71 is the default scaling factor. If they’re absent, the center is the origin (part zero). X, Y, and Z allow you to specify an optional center for the scaling. G51 scaling is available on Fanuc controls, but Haas does it slightly differently. G12 set for radius style cut… G51 G-Code: Scaling G00 Z0.1 M09 (Rapid retract, Coolant off) Īnd here’s a backplot in G-Wizard Editor of that program’s toolpath: Here’s a sample program that just cut’s the radius: If you want to remove all the material, use I and Q values less than the tool’s diameter and a K value equal to the circle’s radius. If you want to just cut the radius, use an I value set to the radius and do not specify a K or Q value. You have a choice–you can either remove all the material inside the circle, or you can cut the circle’s radius only. To use these g-codes, start by positioning the tool above the center of the circle. * = The word is optional and can be left out.
L*: Loop count for repeating deeper cuts. 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. G12 & G13 G-Codes: Circular PocketsĬircular Interpolation or Helical Interpolation is something we see often in CNC programming. Now let’s go through and break down each one to see how it works. G53: Non-Modal Machine Coordinate System.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.
