Thank you gcode! Is it not Plunge turning better for larger size grooves? I use groove operation only when the groove is narrow.

Thank you. Sorry I couldn't share the file. I think the problem is due to the use of wrong operation! I tried to rough a large face groove using Roughing operation. But when I tried Plunge turn operation, I got the toolpath like I expected without any problem. Thank you!

Hello everyone! I am getting this "No areas of remaining stock error" when I try to remove stock from a big face groove using Roughing operation with face groove/ od groove with horizontal holder There is a similar post in this forum but there is no clear solution. "https://www.emastercam.com/forums/topic/75233-simple-lathe-toolpaths-with-stock-update-not-recognized/" After going through most of the Lathe stock problem posts , I ensured the following: 1. Front face of my part and chain is exactly at zero and is not extending into +x axis. 2. Face stock is defined as Margin 3. Used stock recognition 4. Redefined the stock setup and regenerated all the programs. Still no avail! I end up facing the same problem! What cause this error? Also, can somebody please explain the use of "Adjust stock" option in Lathe roughing and how to use it? Thank you!!

Nice! But we have an active license and active SMC! Is it not accessible to those with active SMC?! I read that book! Ok thank you very much for the inputs!

Yes it's good! Thank you! Noticed that there is no html help file in MC2022! Instead there is a chm help file, which we can access from inside of any operation/tool. But this new chm help is very brief. Earlier MC came with html help file it seems, which was having structured and detailed contents! Is there any way to get such html help file for MC2022? Or can somebody tell which last version of MC had such html help file? Just I like to mention some of the youtube channels which have knowledge rich contents, since we are talking about the resources/help files: 1. Mastercam (good but needs to go to MC University to see the full content for many videos) 2. MLC CAD systems (short and good contents) 3. In-house solutions 4. Streaming teacher 5. CamInstructor (discussed many practical problems) 6. ASPE Aerospace precision engineering (shown programming of Aerospace components and having other good contents like accelerated finishing techniques) 7. Colin Gilchrist (detailed videos on post processor) (is it you!?!) All these channels have very good and advanced contents! In our official MC university account (which is linked to the License), there is no access to the latest Multiaxis tutorials. It shows message that to contact reseller for the access. But my reseller says that since it is made free to all because of corona lockdown , some advanced contents are taken down by MC and that only after the end of free access we can get the full access! Why it is so? What can I do to get the full access? Thank you!

Downloaded Moduleworks help file. Mastercam University tutorials are better. Downloaded lot of mcam files from techexchange too. Even many of old post here in this forum gives deep understanding. Thank you!

Understood What I only expect from them is that if they don't know something, instead of telling that such feature is not there, atleast they can redirect to someone or someplace where people knows the answers. We didn't purchase earlier MC because Blade expert is supporting dynamic roughing. Later through this forum, I came to know that it can be done through other tools and then we purchased it! I also very much agree that no know can know everything! Thank you!

Excellent! Had the MC reseller showcased such capability, we would have shifted to MC longback! (but sadly even after showing your post, I understood that they have very little idea about this) Thank a ton Chally!

Barrel tools allows us to use higher stepover and thereby reduces finishing time, but it doesn't give advantage in tool approach/orientation. The axis limit problem occurs, because by default the CAM softwares tries to keep the tool normal to the surface. If there is no option to limit axis in the CAM software, then it is difficult to avoid this problem, especially in Blisk machining, because the machining starts from table tilt with 90 degree. For example, in machining the inclined floor of blisk, it should be possible by limiting B axis to 90 degree, instead of allowing it to tilt further from 90 degree to keep the tool normal. This is a clear software limitation, since I have programmed the same part for the same machine using an another CAM software. But most CAM software does not allow direct axis control with the Multiaxis roughing strategy and it is indirectly controlled by Wall flow lines or Floor normals.

I like to share but I don't have the permission. I will try to model it in my home version but I need some time for that. In the mean time, just I like to add some more detail: It is a jet engine blisk with a inclined floor (truncated cone surface). To machine the blades, the table has to position itself with B axis 90 degree (in a table-table 5 axis machine) and if the floor/hub is inclined, then the table tilts further to keep the tool perpendicular to the floor. When this happens, the tool path exceeds the B axis limit, which is +95 degree in my case. To avoid this axis limitation problem, I used your false floor strategy and it worked fine except leaving a conical stock at the floor (since the false floor is cylindrical but the actual floor is conical). Thank you!

I attempted this technique on a blisk and here are some of my observations: 1. Able to control tool orientation by using false floor and the tool orientation get adjusted to avoid collision with the twisted walls. 2. Plug stock method worked fine without requiring any containment boundary, but it is using the gap between the adjacent blades for links! (since there is no stock between other blades) 3. The hub surface for the Blisk I used is a truncated cone surface and I used a cylindrical surface as a false floor. The toolpath follows the false floor and so lot of stock is left over the hub/floor surface. In Esprit CAM there is "project toolpath down" option in the Multiaxis roughing technique (called as 5 axis channel roughing), which gives a clean and uniform remaining stock on the non-planar floor. Without such option I think it's difficult get a clean floor in Mastercam. Please let me know if there is any other way to get a uniform floor. Thank you!

Excellent! Thank you very much Chally! 1. Does it work when the walls are twisted and comes in the way of normal direction to the false floor? 2. In the case of Esprit CAM, the tool axis orientation is controlled by v-direction flow line of the walls and so I used to create false walls with required v-direction flow line by modifying the edges! Is there any such influence of walls in Mastercam, in controlling the tool orientation? Thank you again!

Thank you Chally! Yes, I am using the full stock! That's really a good idea, instead of using containment boundary Here I like to ask some more related questions: 1. I observed that there is no tool axis control for roughing strategy in Multiaxis Pocketing! Is there any indirect way (like the idea which you gave for containment) to limit the tool axis ? (Many times when I tried to program Blisk with Esprit CAM program, I end up with exceeding my B axis table limit) 2. My reseller (Mastercam India) told to use Multiaxis Morph toolpath (which have tool axis control), instead of Multiaxis Pocketing toolpath, to get toolpath similar to dynamic roughing by opting tool path direction from blade to blade. Is it really a good alternative? 3. (Not related to the Multiaxis Pocketing) Just wondering, in your example mentioned above, how does the center slotting helps when you use Multiaxis dynamic toolpath? Thank you.

I am trying to rough an Impeller using Multiaxis Pocketing operation. I am using this tool instead of Blade expert, to get Dynamic tool path. If I don't use containment, then tool path is created for the complete impeller. I want to rough only one channel and then I want to use transform operation. Now the blades are highly twisted. Using a 2D boundary covers extra zone at some places and leaves cutting zone at some other places, since the blades are twisted. So, how can I contain the Multiaxis Pocketing tool path between the blades? Version used: Mastercam 2022 Thank you.

Thank you Colin! So there is no need to do Stock setup? Are we going to miss anything if we directly use Stock model for the initial stock?

Hello everyone! I just started learning Mastercam. I learnt that there are 2 ways of setting up the stock. One is Stock setup and another is Stock model. Can someone explain the difference please? If Stock model is used to transfer remaining stock between the operations, then what is the use Stock setup in the Machine group? Thank you.

Thank you Chris! Can In-house solutions provide post which outputs NC code with subroutine for 5 axis as discussed?

Thank you gcode & Colin Gilchrist! 1.  You don't say what machine(s) you require posts The machine is DMG mori DMU70 5 axis milling machine with Siemens 840d controller. 2. We ordered Blade expert. But our reseller told that it doesn't support dynamic roughing. They informed that it may be possible using a tool called 'Multiaxis Pocketing' and they are yet to confirm. 3. We machine hard materials like Wasploy, Udimet, Nimonic-90, etc., Traditional roughing never worked out on these materials. Does 'Blade expert' offer any superior method than Trochoidal/Dynamic milling? 4. Manual linking using point option will be great. 5. I was not knowing about 3rd party posts! We ordered with Mastercam for the post. Thanks for the information. 6. 3 axis loop/subroutine is an easier one and I have written some code on my own, which works without any problem. But, 5 axis with RTCP mode is difficult. I attempted several times but failed. When RTCP mode is ON & when we index the table, then the tool also moves in relation to the workpiece and thus it will end up in the same position. I also tried switching off TRAORI command before indexing the table and even tried the Cycle800 to loop. But it never satisfactorily worked. If In-house solution or Postability can provide such customisation then it will be great. Thanks a lot for the inputs!!

Hello everyone! I am new to this forum and this is my first post! I am a user of Esprit 2019 CAM for 5 axis programming of Aerospace components. Recently my employer decided to shift to Mastercam 2022 (because of some commercial policy issue over SMC) and placed the purchase order for Mastercam 2022. I searched this forum and some other sites regarding the advantage and disadvantage of Mastercam over Esprit CAM. I got some useful answers but all are old post (before 2012). So here are some of my questions / doubts: 1. Many points out that Mastercam post needs editing and it is not robust like Esprit. Is it still the case or improved? (I never had any problem with Esprit post and I never heard anything like post edit other post customisation for requirement) 2. Esprit have a "5 axis channel roughing" operation, which is Multiaxis trochoidal roughing operation between 2 walls. We use this operation for roughing of Impellers and Blisks. In my quick search in youtube and Google, I couldn't find any equivalent tool in Mastercam. Is there any equivalent tool for trochoidal roughing of Impellers and Blisks in Mastercam 2022? 3. The two main problems I faced with Esprit are 'Axis limit control' and 'External rapid links'. Some critical 5 axis operation like the one in mentioned in point no.2 does not have axis limit control and the tool axis is directly derived from geometry edges, which results in the frequent problem of tool path exceeds axis limit problem. It is very 'very' difficult to create collision free internal and external rapid links'. You need to spend hours to get a collision free rapid links'. Are these cases same with Mastercam? Or will I be free from these problems? 4. With Esprit we tried to customize the post processor for 'LOOPS'. That is instead of extracting NC code for each individual features of a pattern, only one program will be extracted and it will be looped using macro. This we got it done for 3 axis but couldn't get it for 5 axis. I explained this to our Mastercam reseller and they told they will try but not sure about it. Is this really possible with Mastercam post? 5. What I shouldn't miss asking my reseller? Is there any important technical documentation that needs to be asked from reseller? 6. Esprit conducts 'Esprit World conference' every year. It's a great knowledge sharing platform. Is there anything similar for Mastercam? 7. Any tips or books to deeply understand Mastercam? Happy to join this BIG forum! (never heard of such forum for any other software) Curious to learn Mastercam. Thank you.
