Manufacturing (CAM)

I often use a selected planes (start and end) in drilling cycles and most of the time things go well.  However, when I need it to go well the most, such as when I need to put out a quick hole pattern for an operator things don't go as expected.  A lot of parts I work on are round, sort of like a big wheel hub.  Operation Z Zero is the center portion of the hub.  Clearance plane for the operation and all of the sequences is set to a plane above the center hub.  The hole pattern lies below the center hub on the flange.  About a quarter of the time (maybe less), the resulting post will put the drill pattern out with the R plane at .025" above the flange and will put the tool right through the center hub without retracting to the clearance plane of the operation or sequence.  In order to fix this, I have to select the top of the center hub as the start surface, which causes the drill to run at feed rate the entire distance - but at least it isn't broken.&

What would cause two different users, using the same mfg file, to get two different ncl outputs? I get: $$-> CUTTER / 6.000000SET / OFSETL,  55ROTATE / BAXIS,  ATANGL,  -90.000000 SET / OFSETL,  57ROTATE / BAXIS,  ATANGL,  90.000000 SET / OFSETL,  54ROTATE / BAXIS,  ATANGL,  270.000000 He gets: SET / OFSETL,  55ROTATE / BAXIS,  ATANGL,  90.000000 SET / OFSETL,  57ROTATE / BAXIS,  ATANGL,  270.000000 SET / OFSETL,  54ROTATE / BAXIS,  ATANGL,  450.000000 (Post takes care of overrotation)   Config setting, setting in machine, site, operation, nc sequence?

I would like to make all solid surfaces one color and the part another. This way when I use inheritance and make all the machined cuts there is a contrastin color automatically showing the machined features. Is this possible?   I am coming from WF3 and have found using the new interface a bit of a chalange in regards to how the system selects surfaces.    Thanks in advance, Chris

I cannot seem to get rapids generated at all when using the chamfer mill section of Creo, all the tool return paths are for some reason feeding.  I have tried many different ways, only to have them all feed on the return, even with the lead in and out turned off.  Any ideas?    

Apologies if this is a duplicate email, I am not seeing the previous post     We are seeing strangeness in sketcher (Creo 4.0 M020). It starts with the lines in Sketcher beinging to get larger and then icon representations changing. We have also seen line thickening in drawings. See below froma  machine that is seeing issues in sketcher.     Seen on a range of Dell machines with low end nvidia graphics cards.     We have tried fixing the line width in Sketcher, but no effect.      Many Thanks for any hints      

Hello "additional creo questions" group.   Is it possible to create a circle segment end mill for use in Creo/NC? The relations I know of that define a solid tool don't seem to account for the geometry on this type of cutter.

Hello Programmer,   I need your help.   I found some sequences that Creo has generated “ROTATE” in the CL data (like following pictures), therefore, these sequences need to exchange GOTO positions by using FIL when Creo was posted tap file. Meanwhile, I also have some sequences that Creo has no generate “ROTATE” in CL data which are unnecessary to exchange GOTO positions. Therefore, I want to write FIL (conditionals control) to determine which sequence need to exchange GOTO position or not exchange.    Could you please teach me how to write a conditionals control in the FIL (IF….THEN….) to switch it when Creo  was generated “ROTATE”?   I wrote following FIL but Creo couldn’t work, just for your reference.   CIMFIL/ON,GOTO WR=TEXT(ROTATE/CAXIS,INCR) IF(WR.(ON))THEN  DMY=POSTF(20)  I1=POSTF(7,11)  J1=POSTF(7,9)  K1=POSTF(7,10)  V1=VECTOR/I1,J1,K1  M2D=DATA/CAM,2,V1 $$ USE VECTOR  $$M2D=DATA/CAM,2,I1,J1,K1 $$ SAME AS A

Hi programmer,   my problem is how to generate correct coordinate and C axis in tap file?   I use Mill-Turn type machine to do side machining of part which machine has y axis function (Like above picture shown). However, I have setup "planar machining" in my post file which included I defined output code for G1 and defined C axis of "Option for ABC angle output", but Creo always generated "G1 C0" when planar machining has different angle.       Also I found that Mill-Turn type need to define Z axis direction for Horizontal of coordinate setting which setting different with 4 axis Mill type (Z axis is Vertical), therefore, Creo refer to sequence coordinate then cause Creo generated wrong coordinates in tap file.   Have a good day!!

Can you use the same engineering drawing for the US and Europe Manufacturers?Most of the US Manufacturers follows the First angle projection and Most of the Europe Manufacturers follows the Third angle projection.If we have to send the same casting drawing to the both supplier with their requirement what we should do?Creating multiple drawings for the same model is a bad Idea. During changes in the model causes update required for all the drawingsSo create the same drawing to use both First angle and the Third angle projectionSee this link for the article, how to utilize the drawing program to maintain first angle and the third angle projection with the same drawinghttp://jkparthiban.com/index.php/2017/04/15/creo-drawing-program-utilize-drawing-us-europe-manufacturers/

Hello, l have a long time problem with model accuracy. l understand it´s different from company to company. Company no. 1 is specialist about fine optic lens with high accuracy. Company no. 2 is specialist about rought machining with lower model accuracy. Our company produce a air-ducts. It means 5000 mm long duct, DIA 1500 mm with 2 mm wall thickeness ---> it´s a big difference between lenght and thickeness. Rules that l have to keep: - all models have same model accuracyMy information about accuracy: - absolute is better than relative - set absolute = 0,002 looks fine? Questions:- do you have any expierences with model accuracy? - could you share your "standard" model accuracy? Thanks for informationMilan Bonka

Is there a way to create your own custom unit cells for Additive Manufacturing module?  Using beams or surfaces.   I would like to create a diamond lattice out of beams   I would like to create a face centered cubic out of beams   I would like to create a octagonal, but with surfaces instead of beams. I want the ability to turn on and off selected surfaces, assign a thickness to the surfaces and vary the density, just like in beams.  This would create a closed or semi closed cell structure that is self supporting for 3D printing.  

Hi,   Does anyone have PP for iTNC 530 (Heidenhain) control for Creo3? Thanks in advance.   Bence

Hello Programmer,I met a problem of FIL that I need to get "Fixture offset" value by using FIL, I can't find the number code of "Fixture offset" in the Gpost. Can you teach me how to compile FIL to get "fixture offset value?  thanks!!Have a good day!!Mark Rao

Area turning parameter contains the LEAD_RADIUS option in the entry exit list but it can not be used except for the profile motion.LEAD_RADIUSThe radius of the tangential circular movement of the tool when leading in or out. Used when creating Lead In and Lead Out Tool Motions, and in Build Cut for Profile turning. The default is 0.****************************************************************Sandvik has developed a method for a reverse turning concept (Prime Turning). See article Modern Machine Shop June 2017 page 71 for complete details. Using this concept the tool must lead in using an angle approach and radius value very much like milling allows. Each roughing pass in the area turning must include this lead radius.  Creo Area Turning can be used for Prime Turning if the lead_radius option is added to each pass. Different feed rates will have to be applied to the lead_radius for this tooling and Area Turning has this option by using the APPROACH_FEED parameter.Currently Maste

Hello all,I have a question, to which I cannot seem to find an answer.  I am hoping y'all will be able to help me.In my work, we use plate steel and bend it.  Pretty simple.  I use the Sheet Metal application (Creo 3.0, M090), so that I can flat pattern the parts and be able to tell the manufacturing people what the overall length of the part they will laser out needs to be.I sketch the part in its bent state, and I have been taught/told as best practice (or so I believe).  Make some cuts, and I have what I want.  I sketch a curve that is half the thickness, and then created a parameter, as well as an analysis feature, and tie said parameter to the measurement.  This was, I know what my length SHOULD be.  (see my first slide in my attachment)   In the first slide, its just a 3D view, and the sketched curve is there to be seen.  I have the curve projected to the same height as the points at the ends.When I put the part on a drawing, I no

Have you downloaded Creo 4.0 yet? Printing parts made in Creo has never been easier. Now, you can use the software to set up a tray assembly, arrange parts, and test them for printability before you send them to the printer. Our expert explains how:To explain the basics of tray assembly, let's start with one part.Selecting the engine cover to create a tray assembly.You can prepare that part for 3D printing, then use automatic positioning and add other parts.Place as many parts as you want into the tray.Adding a fuel cap to the tray assembly.You can also create a pattern, which you can use to create multiple instances of a part. For example, select one part and then define the pattern, then select the number of parts. In this case, we are using direction. You only need to worry about the number of parts.Creating a pattern of the parts using Direction.When you click Auto-position, the system arranges the parts inside the tray.The parts are arranged automatically inside the tray.Let's cre

I recently updated Creo 2.0 from M090 to M240 and noticed on a couple of occasions that I am getting some flats in the tool path when using Cutline to Circle Interpolate a hole.  I have seen this before and can sometimes fix it by loosening the tolerance, but it has been a long time since I've seen it and I do a fair amount of this.Is this anyone else has noticed or am I alone on this one?Matt

My goal is to be able to add or edit CL Data in any area of the CL code, so that the edits stay in the manufacturing model in case they are coded out at a later time. According to these PTC instructions Creo Parametric Help Center, it should be easy and available right in the Play Path box.  This would be extremely useful, however I do not have the option, mine is greyed out and unselect able.The only other option that I can find is by going to manufacturing tab and then selecting Edit/CL Command, however this only allows me to select "beginning" or "end" for my placement of code, and does not allow me to specifically place lines of code like I am attempting to do.  In this mode I can also select Edit/Edit Mode in the code window and change the code and then save it, but it does not seem to keep my added CL Code.  I just want to be able to add or edit CL Code on any line that I desire, anyone have any ideas?guys.Thanks again

Curious if anyone is putting derived from (saved from) information on their drawings.  It would help our manufacturing department to know where a model was copied from since often times they already have the machining programs written for the original models.  Windchill can provide "saved from" information, but this is only available when the save-as event took place inside Windchill.  Frequently we do the save-a-copy from Creo itself so the table in Windchill is empty.  Creo files do have an internal history log, but I don't know of any way to expose this information on a drawing.  I imagine we could use a parameter and just type in dumb text, but I'm concerned about this being done correctly and consistently, not to mention that a rename in Windchill would create a complete disconnect between this dumb text and the actual model names.  Any suggestions?  Does anyone else provide this type of historical information to their downstream users?  Tha

Hello,I would like to suggest a small improvement  to library component editor: It should have a field for Tags. When we are searching for a component in library, we don't  always remember the name of the file, specially if it was made by someone else.In this example, I would use tags like: Cashew gate, Tunnel gate, Curved tunnel gate, Gate insert, tgs, etc...Then when we make a search, emx search not only for filenames but also for this tags.Thanks,Jose.

Hi!  Are there any plans to include machine kinematics simulation along with Material Removal Simulation in ModuleWorks?This combination of simulations would be extremely useful!! I have not found any way of combining this so far.
