Saved me from quite alot of work on my last day before holydays

Hello guys, I have the same problem as described.. Could someone please check/open my file (since I dont have RG) and tell me the UFRAME 1 and 2 values.

Thanks in advance!!!

Trully thankfull for this answers!

Best regards

Which one would be the easyest to use (less complications) and which one would be the cheapest?

Regards

Thanks guys! 1 more question.. What would you recommend if the machine doesn't support I/O that you can use in its ladder?

Regards

Thanks a lot guys!

Regards

AB is a brand i suppose? And PAC?

We are based in europe so siemens would be the way to go probably..?

Thanks for the detailed answer or explanation! Our CNC's have some I/O's but they are very limited I would say.. Maybe an input for cycle start and output for cycle end, but as you said the doors would deffinetly need some upgrades (limit switches). Chucks are hyduralic so I would just use a relay instead of a pedal. We will try to avoid turning stocks, but if the stocks vary only in lenght (turning) it shouldn't be a problem as long as we use some kind of pressure piece on our gripper.

When you mentioned an interlock you meant a chuck interlock?

Hello guys,

we are in the early stages of becomming a Fanuc integrator and I just want to hear some recomendations on what brand and type of PLC should I chose for future projects? What do u guys usually go for?

Hello guys,

at our company we are about to automate our shaft/gear production but we are curently using older CNC machines (the machines are in good shape), they were made betwen 1975 and 1995 and I was wondering if any1 has any "tips&tricks" for automation with older types of machines or things I should be carefull about.

Thanks for the help in advance!

Regards

Best of luck!

Hmm difficult project no doubt.. sorry I couldn't be of much help.

Let me know how you solved the problem when you do! Best of luck!

Maybe still ask Robotmaster for any ideas.. They eaven send me a video of simulation for my project.

So where the lines are skipped there is the problem?

What if you would "cut" the piece (in CAD) in multiple pieces and then make paths with OLP for each surface? Could you draw on the pic attached exacly where are the surfaces you cant reach?

I can't suggest anything that will work for sure, but you could try to contact RoboDK or Robotmaster (or any other OLP software retailer) and ask them how would they go at it.

You said that you cant get to all surfaces by programming with OLP... are u using 1 grinding tool or multiple?

My pleasure!

Regards

Do tou need to grind the part from different sides? If I rephrase it.. do you need to regrip the part multiple times to get to all the surfaces? (In case of RTCP).

And also if you would create a G code program in NX or powermill and then use roboDK to make robot paths that would require a really precise model and robot.

What are you're required tolerances?

And I'd like to add that I'm in robotics for about a year so "don't hold for my words" if you know what I mean... just trying to help

Thanks for the info guys! Appreciate it.

What max payload should a robot for a job like this have?

And what could we achieve with this one?

Thanks for the answer!

Hey, I'm not an expert but..

Could you share the a pictue of the part?

Anyway you will have to use RTCP like in the videos you have shared.

What CAM software do you guys have?

Do you need to polish/grind or really remove material (more than a few 0.1)?

Gear material is different from gear to gear but the most common is 16MnCr5 with 25-30 HRC.

Accuarcy req at chamfer 1/45° is 0,2 mm and at 3/45° 0,5-0,8 mm.

Cycle times also differ from part to part (some gears have 104 teeth and module 4-small teeth some have 16 teeth and module 20-big teeth), for a gear wtih 104 teeth and module 4 our worker needs 35-40 min for bolth sides. So anything below 20 minutes (10 min each side) would be great, also a big problem with manual labor is consistency.

4 or 5 axis cnc is too expensive, and with a regular 3 axis cnc we cant reach the gear from one side because some of the gears we produce have a shaft extending from the gear's face so a 3 axis machine could not reach in most cases.
