    Fillet at Impeller root radius

    I am trying to put a uniform fillet between the hub and blade of an Impeller. However, the fillet radius is changing near the leading edge. When I check the iso-parametetric curve along the blade, before making the fillet, it is uniform from top to bottom (shroud to hub). However after making...

    Guidelines/Best practices for 3D Modelling of Complex drawings

    Greetings Mechanical Engineers! I request experienced mechanical design engineers to suggest guidelines/best practices for doing 3D CAD modelling of complicated enginnering drawing. I received a complicated casting drawing for 3d modelling, which consists of 12 A1 sheets with 100s of views and...

    Is it possible to find the location/position from the given thickness value?

    Hello everyone! I have an airfoil blade model. Its thickness varies from top (shroud) to bottom (hub) and from right (Leading edge) to left side (trailing edge). Is there a way to extract the thickness distribution at a section? Also, it it possible to find the location/position by taking...

    Effect of Datum accuracy on the controlled feature

    Can the controlled feature be more accurate than the datum? For example, if the positional tolerance is called with reference to a flat datum with the flatness control (say, 50 microns), then can the positional tolerance be less the the flatness value of the datum (that is less than 50 microns)?

    Impeller/Blisk Multiaxis roughing

    Hello everyone, I am new to NX CAM although I have experience in NX CAD. I am in the process of shifting from Esprit CAM to NX CAM and so I am trying to figure out whether all the major feature in Esprit CAM is available in NX CAM or not. One such feature is Impeller/Blisk Multiaxis adaptive...

    How to exactly divide a face where there is change in curvature?

    I have an aerofoil blade with single face. I want to divide the face where the curvature changes, for treating the portion separately in CAM software. By doing curvature analysis, I am approximately picking the nearest isoparametric curve to divide the face. But is there any better way of doing...

    Midsurface tool problem for complex geomtry

    Whenever I use the Midsurface tool for thin complex geometry, the result is always not accurate. For example, when I use the midsurface tool to create midsurface for an axial aerofoil blade, the resulting surface is not exactly at the middle and sometimes some portion of the midsurface overlaps...

    Data loss while exporting

    What is the best practice & format to control data loss while exporting the model? I created a midsurface for an aerofoil blade using 'mid-surface' option. It looked fine (i mean, exactly at the middle) in the NX, but when i import the model in another CAM software, I found the midsurface was...

    Journal to extract face normal information along a curve

    Does anybody developed Journal code or Grip function to extract point and face normal (x,y,z, & i,j,k) information along a curve? This information is required by the CMM inspector for the model to inspect. I am able to extract the information for a single point (by creating information of the...

    Best Practices to prepare CAD model for CAM

    Are there any best practices to follow regarding CAD model preparation for CAM? Nowadays, most of the CAM are feature based CAM, which is going to use the CAD model for tool path generation. Hence, the accuracy of CAD model affects output of CAM. So regarding this, I have the following...

    Is it possible to create mirror along a curve?

    Is is possible to create mirror curves along a curve? Like an offset, but the curves has to be mirrored along the selected curve instead of simple offset.

    How to limit selection to a particular volume?

    I have a complex model. I want to select the faces/edges within a volume which I make over the existing model. For example, in the existing model, i want to create a hollow cylinder and then i want to select all the faces/edges which falls within the boundary of this hollow cylinder. Any help is...

    How to create Cross sectional area curve along a given path?

    Is there a way to create Cross sectional area curve along a given path (defined by a curve)? The space-finder tool gives a Height vs Volume relation curve. Just like that, I like to draw a cross-sectional area curve along the given path. Is there any work around to do it automatically instead...

    How to check the distributed mass?

    For example, How to check the mass distributed per unit length along the axis of impeller? Is there any option to check this in NX? Thanks

    What is the best procedure to follow, when making 3D model for Meshing/FEA?

    Is there any procedure or method to prepare 3D model for Meshing/FEA (in other software like ICEM meshing) ? When I prepare a 3D model and export that to a meshing software like ICEM CFD, I am getting the following problems: 1. The 'connected surfaces' in the NX, is showing as 'unconnected...

    How to select the connected inner faces all at once?

    How to select the connected inner faces all at once. For example, I have a hollow pipe which is lengthy & bends in many directions. I want to select all the inner faces of pipe at once, without individually selecting the faces. Is there anyway to do that? Thanks

    How to set part name different from the file name?

    Generally I save the part file with part name and part no. (eg. Shaft (01-23-456)). So in the assembly part list, the part name displays as 'Shaft (01-23-456)'. I would like to display the part name and part no. separately in the corresponding cell of partlist, in the assembly drafting. Is...

    Copying Title Block contents?

    Is there any method to copy contents of title block from one drawing and to paste it another drawing? I would like to copy the title block contents which mostly reoccurs like material spec, heat treatment, protective treatments, name, etc., from 'old drawings' and to paste in the new drawing...
