Haas CNC Control: Recording Cycle Times

Dear Answer Man, What facilities are on the Haas control to record/monitor machine cycle times Andrew Dear Andrew, The Haas control has a number of built-in timers that may be used to monitor cycle times. Under Current Commands, page down to view the “Program Timers Display” page, where cycle times can be viewed. Operation Timers Display: This display shows the current Power-On Tim [...]

Setting Up the Post Processor on a CNC Mill

Dear Answer Man, We just purchased a VF-2 CNC mill and are in the process of setting up our post processor. We hard-wired it to the machine and are using Surfcam. I have one problem, at the end of the program the machine will move up in Z to 1" above the part, and then it will move back down to the Z pick-up surface of the part before going up to the tool change position. That could be a proble [...]

Definition of “Modal”

Dear Answer Man, Hello, in reading your Operator’s Manual, I see the words modal and non-modal used quite often. Can you please give me a definition of modal? Jan Dear Jan: When a code is modal, it means the programming code stays in effect until it is cancelled by another code or another action taken by the operator (pressing the Reset key, etc.). When a code is non-modal, the code [...]

CAD/CAM Interpreter G-Code Errors

Dear Answer Man, Do you know of any PC-based G-code interpreters that closely match (or identically match) the Haas interpreter on the Mini Mills? We have many students learning to use the Haas machines. When they generate G-code (using Virtual Gibbs), the Mini Mill inevitably discovers errors with the code during screen pass. Rather than waste valuable machine time, it would be better to have [...]

Alarm Simulation Software

Dear Answer Man, Do you have software that will simulate a new program on a PC, and show the same alarms that I would get from the Haas control? We program using a CAM system, but we still have a few problems when we load a program into one of our Haas machines (we have five), and then it takes up time on the machine to troubleshoot the program. Tony Palazzo Dear Tony: Given the number [...]

Three CNC Programs in One

Dear Answer Man, I am trying to run a 3D program on my VF-3. It’s too big to fit on a floppy, and we cannot send files from PC to Haas yet. Is there a way that I can take the three programs that actually make up one part and combine them on the Haas? I am looking for a way I can run this part overnight, without having to come in and call up another program. Dave Bartlett Dear Dave: Y [...]

Sub-Routines on a Vertical Machining Center

Dear Answer Man, I have a question about subroutines on my VF-6. I want to mill the same contour in several places – a 10 x 10 mm rectangle, repeated 100 times. What’s the best way to do this? Gunnar Gustavson Dear Gunnar: It’s pretty easy. Here is an example, in inches, of calling an incremental (G91) pocket subroutine from within a main program. Main Program: O01235 T1 M0 [...]

Programming Constant Surface Speed

Dear Answer Man, I have a question about one of the programming examples in your operator’s manual. Here’s the example in question: T200 B-2.0 G50 S2500 G97 S1042 M03 G00 G99 X2.0 Z0.01 T232 M08 G96 S600 G01 Z0 F.01 What is the purpose of the program line that has G97 S1042 M03 in it? I ask because of the G96 S600 code that follows two lines down in the program. This just does [...]
