If you have never heard about G187, or you've heard of it but never used it, this video is a must-watch. G187 is a standard feature on all Haas mills, knowing how to properly use it can make a huge difference in both cycle time and surface finish. As always, Mark takes a potentially confusing subject and breaks it down so that even a beginner machinist can understand it and make use of it.

I have to agree this is an actual useful TOTD, most are pretty useless but this was informative. What would have been nice was to include the E parameter as an override outside of default P1,2,3 settings.

@jaymachines7587 5 лет назад

G187 is our best friend we use cutters below 1mm all the time and cut extremely small parts that require 3D machining and superb surface finish. I use the P1 with a big rad for my adaptive roughing and then P3 E.005 for finishing it works great!

@marc-antoinethebeautiful7714 5 лет назад

Does the smooth command bug if you put a g42 or g41 with a dia comp greater then the tool path in a 5 axis mode in the retract motion before the cancelation of the smooth command? You may ask why do you do that. On the first article an operator may want to test cut his way into tolerance where he may try to cheat by putting a dia-comp of let' say .040 of an inch on a 1/2 endmill to measure then compensate. Luckily it was showing on the tool path . But my programmer didn't believe that it would LOL. So the question is will it do that too on a haas control? It's a bug that I've discover but never got answer from the other controller manufacturer. Thank you in advance for taking time to answer the question.

Hello, I have a question. I tried to use The “rough” and “finish” setting on our old Haas VF1 machine and every time I ran a program with either rough or finish setting The machine ended up with an alarm 178 ( divide by zero) It happens every time The tool is in its Position to start milling Could you help me with this one?

@MM-wp5sp 4 года назад

This is a problem with HAAS control. Every other control on the market including Fanuc, Siemens, and Heidenhain, has no problems with HSM. No special code or whatever needed. It just runs, smoothly and efficiently. This is an old oroblem with HAAS controls. As we can see from the video, they still havent resolved it. Really, HAAS?

@markterryberry4477 4 года назад

M M, check for "smoothing" on your control. Chances are they will have similar options to control smoothness. The physics we adjust for with a G187 would apply to every CNC machine - or Tron bike :)

@Metalbass10000 4 года назад

I always taught my programmers to examine the prints, all inside radii, all size and finish tolerances, and only THEN start selecting tooling for any pocketing or contouring with inside corners/radii. I was always amazed by machinists with 20, 25 years experience that used, "on size," cutters as a preference, then called out for help because they have chatter and a shit finish. What amazed me more was when my boss, with 35 or more years experience would insist that was proper and correct for smart efficient machining. Some days...

@holdilocks 4 месяца назад

I worked at a place that only had 6 Cat 32 holders for their Vetical Mill, I was forced to use at size tooling in order to do all the other features - drilling, facing and tapping. It was like pulling teeth to get worn out tooling replaced, had to sharpen drills until they were too short to work.

I've been a machinist/programmer for over 15 years and it never ceases to amaze me the little tips and tricks I pick up from these Vids. Excellent content. We only have 1 Haas in our shop, the rest of our mills are German DMG's, our company bought bc "we want the best". Our DMG's are constantly down, and our Haas has only been down twice, ever. Once when it was knocked off its moorings by a careless forklift operator and once when I busted off our tool touch off probe arm, while cleaning the bed, both times self inflicted. damage.

@raunaqahuja6047 5 лет назад

Just leave a bit of extra leftover stock or finish margin (say 0.5 to 1mm ) in case you're using G187P1 coz the tool tends to overcut . You can save about 30% cycle time for sure.

Might be a silly question, how do you work out the E value? Im looking forward to trying this. Hopefully it will save me hours of blending in with sandpaper 😂. We do a lot of vacuum forming tools from aluminium. Would appreciate it if you could get back to me or if anyone else can help that would be great. Cheers

@haasautomation 5 лет назад

Phil - If doing mold work, I’d do some test cuts. You can use a G187 P3 E0.01 (if you work in inches), and see how things look on a small mold. You can reduce the E value, to something like E.005, cut again and compare. If you see a noticeable difference, you can go with the E.005 instead of the E.010. In general, the lower the E value, the longer your part takes to run. On some types of molds though, I’ve seen no cycle time difference by going with the E.005 instead of the E.010 -but my finish was also just fine with an E.01 on those molds. If you’re using a G187 P3 E.01, you can’t go wrong. Thanks for the question. - Mark, Haas Tip-of-the-day

Would you not just take the precision of the machine.... double it for "safety factor" call that P... Take the radius of the tool call that R. Then cut the corner by R subtract P.... Max corner cut! given current tool radius? Why would you not do this?

@bajasoobnut 5 лет назад

In a Haas as old as the one I am using all the time I can only use the e value with the g187 code as the p value is useless and ignored due to the software onboard. So when I use dynamic milling I set the e to E0.025 and makes a big difference for sure and then with finishing I leave it at E0.0002

@joshuaboulee8190 4 года назад

I have a 2014 and the g187 P values seem to make no difference. Identical features in 2 different work offsets, one will make a seamlessly smooth circular path and the other will pause at 180° around the circle, like exact stop is on. I'll try the E values now though, I didn't know they existed!

@dstryr932k 5 лет назад

Great video Mark, thanks! I've got a couple of questions, within the control parameters there are some parameters that seem to define acceleration for each level of smoothness, for high speed machining option enabled machines, that is, How does these parameters affect the acuracy and acceleration?

@shawn01707 5 лет назад

Number one issue I have with engineering models is they don’t account for the radius of the cutter. They have cool features in the model that are not necessarily needed in the part that take much longer to machine. Mostly though is sharp corners that are not necessary

@joshuaboulee8190 4 года назад

I agree with Shawn. My second most common issue I see with designs is specifying threads unnecessarily close to the bottom of a blind hole, with no consideration given for any chips that may pile up in there or the thread lead on a tap.
