Fusion 360 CAM - Program 4th. Axis Tombstones -

[@rsm169]

What a great video. I was able to use all of your techniques very easily. Thanks Lars!

[@cadcamstuff]

Awesome to hear. Thank you for watching

[@GTFab]

Great video Lars. I've been waiting for a 4th axis tombstone video for a while.

[@cadcamstuff]

Thank you GTFab

I realize it is quite randomly asking but does anybody know of a good website to watch new series online?

[@leonardoparker1364]

@Jermaine Zaid Try Flixzone. Just google for it :)

[@ishaanbeckham595]

@Leonardo Parker definitely, have been watching on FlixZone for years myself :D

[@jermainezaid1702]

@Leonardo Parker thank you, signed up and it seems like a nice service :) I appreciate it!!

Great video Lars! I’m new to the cnc community but I love cnc Mills. I recently got my first cnc mill and I was wondering if you can make a video on how to set up A axis in a Haas machine and how to build the Rotary A axis and how would you program a part not with the wrap tool in fusion 360?

[@paulketcham9905]

Lars, nice video. I'd love an expansion video on this subject. Specifically, if I have a 4-side tombstone (the vice variety like presently sold by Chick Workholding). Each side has 2 positions and all 4 sides have the same part; the top position on each side (OP1) and the bottom position (OP2). Let's assume the parts have 6 side to machine. My question is, keeping the idea of amortizing tool change (minimizing the number of tool changes) between OP1 and OP2, AND hitting the 2 exposed face AND the 4 exposed sides on the other 2 sides. Once this is done, then we index 4 times, and 4 complete parts come off. Whew! Thank you for your thoughts, but this would be a great video and it could be integrated into a vertical machine scenario as well with the same part, OP1 and OP2, in each of the 2 vice positions of a double station vice, with 2 or 3 vices.

Thank you Lars. I cant wait to program my tombstone now. I am still working on positioning the parts on the tombstone. One thing I noticed is there was no additional clearance of the tool while the pallet is rotating. Does that have to be done manually? Ryan

[@GTFab]

Good question and I had the same thought. I'm not certain but at 21:48, line 87 (N390) there is a G30 G91 Z0 which is not present at the end of the other facing operations. G30 is a secondary machine home position. I'm assuming it is configured as a safe position for tombstone rotation and the code is inserted by the post whenever the tombstone is indexed.

[@50STUNT]

good eye! Full retract to home is pretty excessive though, but better than a crash.

[@cadcamstuff]

Good eye! Without digging deep, I would think you could get you clearance plane to be your height for rotation. Or, use a manual NC comment between Setups to set a rotation height....maybe something I need to try to look into next week. Best, Lars

[@50STUNT]

Well, I have made a few mistakes in the past and broke cutters off by copying and pasting code with incorrect clearance for rotation, so home position clearance will save me some money on setup!! I am very excited to post the code and run parts today with no manual editing. I like to keep all planes very low from part to part, no higher than .1 above stock, so I really only need high clearance for rotation. Thanks again for the video Lars!!!

[@roberth270]

thanks for this video, answered alot of questions i had about multi setup/axis work in fusion. now to go and play :) keep up the grate work.

[@cadcamstuff]

You are so very welcome :-) Thank you for watching!

[@derekmark3847]

Is there a good video that deals with building out the tombstone and fixturing and attaching the vises and sub plates and such, and making the parts orient in them correctly? Thats the part I am trying to understand better.

[@iDiveDOTtv]

Hey Lars Excellent video. Always easy to understand your concepts and you've taught me loads about Fusion :-) One thing I don't understand though is how does fusion know where the centre of rotation is? On the second example I suppose it doesn't need to know. It just remembers X, Y, Z, A in space and orients it that way. On the first example is the origin also the centre of rotation? So say if I had a two sided tombstone I couldn't touch off at the back corner it would have to be on the A axis centre line? Apart from the above amazing as always :-)

[@cadlabCNC]

Good stuff.!! I completely understand the episode!!

[@TBevins]

Great vid, not too much info, that's exactly what it takes , thanks!

[@cadcamstuff]

Thank you Tbev

[@evandrofernandesmendes2152]

Parabéns professor muito boa suas vídeos aulas 👏👏

Thank you Kevin L

[@neilsmith5930]

Great video again thanks Lars

[@cadcamstuff]

Thank you Neil Smith

[@CharlesAlanRobinson]

Thanks Lars. Good info.

[@cadcamstuff]

Thank you Charles Robinson

[@riddlemaster91]

If you need to rotate to hit another side of the part is there a quicker way or just creating a new set up each time?

[@johngover1455]

Thanks for the video Lars, Is there a way to machine the two different parts, on two different sides of the tombstone, presumably with two separate setups (in order to define the tool orientation / tombstone side), but also be able to minimize tool changes? For example Part A on side 90, Part B on side 180...T23 on part A, then T23 part B, then change tools to T40 for part B, and move to T40 Part A, etc. (tool numbers are arbitrary of course). Basically making some operations that use the same tool on the two different parts shown in this tombstone video, completing all operations on all parts with a given tool once rather than changing in and out of the spindle. This is useful for manual tool change machines with or without additional axis as individual parts could be programmed, and then grouped on a table or tombstone as needed. Making mirror parts, full component sets, etc rather than large numbers of the same component.

[@cadcamstuff]

Hi John Gover Thank you for watching! Right now there is not a good way to mix everything up like that, but I know that the development team is working on some cool new function that could speed up that scenario :-)

[@johngover1455]

Thanks for the reply Lars. I wasn't having any luck with the methods I was trying ;-) Great to see the quick responses to questions, even in semi-obscure methods of asking (in the comments of a video). Autodesk- Give Lars a gold star for the week.

[@mapletraffic8086]

Nice information thank you

[@Zenjoksss]

Thanks a lot. I understand what I can't understand long time

[@josepenaloza1783]

What if on the second wcs. You face the part like you did but also wanted to drill holes on the side of it ??? How would you go about that ?

[@cadcamstuff]

Hi Jose Penaloza Thank you for watching! As long as you can use the same wcs direction, you can create drilling toolpaths on other parts. Hope this is helpful. Best, Lars

[@josepenaloza1783]

I ment on the same part that gets faced can you create drill toolpaths to come in on it's side with tool orientation? I've given it a go but no luck. Maybe you can't do that ?

[@grappler185]

Could you do another 4th axis tombstone video where you show how to do operations on three sides of two different components. Component A mounted at the top of the tombstone and a completely different Component B mounted at the bottom. Do all the processes to all sides facing the spindle on all six parts, rotate 90 degrees, repeat, rotate 90 degrees, repeat, rotate 90 degrees, repeat. Really appreciate your work.

[@cadcamstuff]

Hi grappler185 Thank you for watching! I will put that on the list! Thank you!!!

[@grappler185]

Thanks!!! Let me know when you post it.

[@grappler185]

Sure would like to see a Part 2 to this video that shows how you handle work offsets for all three sides. : )

[@47alexb]

Is it smart to use pattern as you can't measure all 4 workpieces sperately by doing so? Would a proper setup not use different WCS for each workpiece?

[@frankr608]

Question on the second method WCS, so would you probe Z like you would X, and probe X like you would Z with a Renishaw Probe ?

[@cadcamstuff]

Hi Frank IRAQVETUSMC1-7 Thank you for watching! Well, on a horizontal Z is still along the travel of the spindle just like a vertical. So you will still execute the probe using XY to locate the corner and Z for up and down. Think about it like you lay your machine on the side :-)

[@hikolanikola8775]

i dont like the fact that simulation doesnt show you the actuall rotation of B axis, because im always terrified that i forgot to retarct the tabe before doing rotation and that it will collide with the spindle :D

[@keefmeef]

thanks for the tutorials Lars . advanced question. can fusion post subroutines using G10? i have a horizontal with 40 parts per tombstone. each part has three sides that needs machining. rather than have 120 wcs' im hoping to have three wcs', but with a wcs shift for each part derived in the code (so it can be nudged on a per part basis if required).. eg. G10 L2 P.. X.. Y.. Z.. thanks in advance

[@cadcamstuff]

Hi keefmeef Thank you for watching! Yes, I know that there are specific posts that support subroutines. You probably want to test one of the ones out on the online library. Also, here is the link for the post forum if you need more assistance: forums.autodesk.com/t5/hsm-post-processor-forum/bd-p/218 Best, Lars

[@meme-hj5rs]

Great video as always . May i recommend a better video quality ? its kinda blurry and isnt possible to clearly see all the text/commands Regards

[@cadcamstuff]

Hi me shkruaj Thank you for watching! Make sure you have the video quality set at 720p by hitting the little gear in the lower right. Because it is streamed it is not created in the highest resolution, but you should be able to see the text for sure. Hope this helps. Have an awesome day!

[@efishnc]

Lars, Great Info, Thanks. However, I would like to know if there is a way or a post that will swap axis. We have old horizontal boring mills with manual positioning Universal heads mounted to a extending ram .. So a lot of times we will program straight on as normal, but quite often will we have a piece setup mounted to that table so we will position the head 90 deg perpendicular to the table . This means we have to swap out the Y axis for the Z axis and use G18 instead of G17. but we still use G54. We have other CAM software that I was able to modify the Post to do this but we are trying to move towards a one source software . Is there an existing post out there for fusion that can do this? I don't consider this an advanced thing, as I can use secondary software (NC Text editing ) to swap axis, but would like to be able to do this using the features you showed here. Thanks

[@cadcamstuff]

Hi erik gerth Thank you for watching! That can for sure be done. If I was you, I would post that question here: forums.autodesk.com/t5/hsm-post-processor-forum/bd-p/218 I know the post team are watching this place and someone might have an easy button Best, Lars
