I have been asked to teach a 5-axis/Advance Mfg class at a local community college. To say the least I'm very excited to be able to pass on knowledge, given to me by great mentors and self determination . However,I have a very limited time frame to create a curriculum and I wanted to know if any teachers/instructors here have a outline they are willing to share . We will need to cover 4th, 3+2 and full five in a 16 week class. I have a good idea how I want to approach it ,but the local CC have never taught this class. So any info you all are willing to share would be appreciated. Of course I would be wiling to share the final outline to help others.

Thanks in advanced.

I am in the same with ya.  I have about 8 months to get a curriculum together for our local cc where I will be teaching.  They have a Haas Super Mini-Mill with a bolt-on 5-axis trunnion.  We picked up a very small Raptor like fixture for holding parts.  The tallest part we can use is only 2.125 inches which leaves only about 4 inches for a tool length.  Not very big but good enough for someone to learn 5-axis concepts.  I have a model of the fixture and workpiece blanks we will be using.  I also have the first part modeled up which will be just 3+2 to teach A/B angles and direction of rotation.  Other than that I am also looking for suggestions on curriculum and sample parts.

i use the stuff karlo puts out for his multiax class, in my class. he has so many examples there, it makes going thru the curricula i use a breeze. i have combined the multiax part of the getting started series with some of my own stuff. if anyone wants to see what i have done, i can share with no problems. in PDF form though, the size is 16 megs. let me know if you want it emailed or put on the ftp site.

[Chris Rizzo]

Sounds like a lot of us are in the same boat. Our college also recently acquired a small (hrt 160) haas trunnion, so a dedicated multi-axis class is now a reality. This summer I'm going to be constructing a course. Trevor yes I'd love to see how you do it.

I'm happy to share all sorts of my level 1-3 material I've generated over the years. Handouts, pdfs, mini-lessons, mini-videos, etc etc. Could we instructors maybe have a quarantined/protected section of the ftp?


Kyle- Great meeting you the other day! The world certainly is small. Our semester just finished and I'll be in touch shortly.

I'm glad that this is finally being offered.  I'm going to being taking classes again this fall in charlotte and I'll probably be in your class in the spring.

thanks.

scott...did you get the email?

chris...how big of a file can i email you? do you have a ftp i can upload to?

a dedicated spot on jay's ftp site would be great. i would like it secure also.

[kklaver]

@ Chris, I would love to see the class material you have. I can hook you up with an Yousendit account if the ftp is not available. Yea, it was pretty cool to meet you this week. I will definitely be in touch.

@ Will, I will call you early this week.

@ Jay, If you are willing to share your class outline I would be grateful and anything I have would be available to you too.

@ Scott, Unfortunately I only have about 2 months. We have a Haas VF1 w/vTR160v( full 5), VF2 w/ 2 indexing tables bolted together ( positional 5) and a Okuma VMC w/ Nikken 4th/5th recently consigned by Okuma ( full 5). Pretty luck to have lot of equipment to work with. We do not have any real good work holding. Did Rapture donate or did you have to purchase it?

@ Trevor, Thanks for the recommendation. The MC default files was on the list to review for class material. Any recommendations are welcome. I would love to see you projects. I can hook you up with an Yousendit account to if you want?

@ Racingdave, very cool. I got to meet a few students at CPCC last time I was there, I llok forward to meeting you.

I appreciate everyone response. I will send eveyone a PM with my email so we can communicate in more detail.

Thanks,

Kyle

Trevor call me and I can set that up for you.

[depasquale]

I am interested in seeing some of what you have done. can you email me in pdf form?
jack.depasquale2960@gmail.com .  Thanks !!!!

[Scott Lundin Shopware Inc.]

Trevor, thanks I did get your email.  Is that the same pdf that is on the mastercam extranet?
Kyle, It was not a true Raptor device.  It is an off name brand and I think it was less than $300.  If I can find it I will send you the name.

[Jay Kramer @ Precision Programming]

It is not the Techno Grip is it Scott?

[Trevor Bailey]

@scott...part of it is. the beginning part. i then pulled in other resources i had.the 3 main sample files in the beginning are from the getting started series, other than that, it is stuff i have added and used over the years. most of the stuff i get is from karlo or rosa.

[Jay Kramer @ Precision Programming]

Ok guy send me an mail. I am going to create a space for us to share. I need emails to send user and pass to you guys.Kyle, Chris, Trevor ,Scott and Will of course

[Chris Rizzo]

Thx Jay!  I sent ya a pm, with email info.  I look forward to sharing all the stuff I've found works in class.

We mounted the trunnion yesterday and started testing it out.  I attached some pictures of the clamping device.  The name on it is 5th Axis and paper work says San Diego CA.

There is not much space on this Haas mini mill for 5-axis work.  The first issue we ran into was with the unit mounted in the center T-slot there was not enough stroke in Y axis when A was tilted to +90.  Moved it to the back slot where it hung off the back of the table about an inch so. We then changed a Y-axis stroke parameter so students don't slam it into the Z-axis sheet metal on the column.  The next issue was G91G28Z0.  On this Haas mini-mill G28Z0 is not at max Z+ position, it is tool change height for the carousel. This would slam the tool into the part.  Along with this is the fact that an M06 also goes to the G28Z0 position.  To get around this problem we changed the post to output the following for every tool:

G90G53Z4.45
G90G53X-8.5Y0(moves the tool to an X position between the part and the carousel)
T02M06
G90G53Z4.25
rapid XY to part
G43H2Z.1
cut the part
G90G53Z4.25
M01

We also changed the post to output G90G53Z4.25 before each A or B rotation.

We started to do some air cut testing and noticed that as it ran and and re-positioned the B-axis in 90 degree increments several times, it slowly started to lose its position by about 2 degrees.  The machine would then alarm out with a TT? B-axis servo lag error.  This a brand new Haas TR-110 trunnion.  Not sure if it is the unit itself or some kind of encoder parameter that needs adjusting.  I noticed when indicating the dove tail fixture that when reversing B direction with the hand wheel there was no indicator motion for a full half revolution of the hand wheel - backlash?  Will play with this a little more but looks like Haas will have to get over here eventually.

Does anyone know what parameters I can use to limit A- to about 20 degrees and A+ to about 120 degrees?  Need to prevent students from rotating too far and hitting that Z axis sheet metal on the column.
