    Cusp height to Surface roughness in Ra calculation

    This seems like it would be an easy thing to find the answer for but after many hours of searching I cannot come up with it. I can easily calculate the cusp height for machining a surface with a ball endmill and a given stepover but I cannot find a formula for calculating the theoretical surface...

    Part Spun Outline

    In turning I can select the part in Geometry -> MCS_Spindle -> Workpiece -> Specify Part and the Part Spun Outline gets created for me. I would like to do something similar in milling; the part that I am milling is cylindrical with radial grooves and many flats on the cylinder body, so the blank...

    required chucking force for horizontal lathe

    What I am looking for is - if I chuck a hollow cylinder in a horizontal lathe, how much force is required for a chuck jaw (the one at the 'top', that is 12:00 if viewed from either end of the cylinder's axis) to retain the cylinder? I know that coefficient of friction factors in to this, and I...

    moment calculation for chucking a hollow cylinder?

    Please forgive me if my terminology is not correct, I'm here on this forum precisely because I am not well versed in this topic... What I am looking for is - if I chuck a hollow cylinder in chuck mounted to the spindle of a horizontal lathe, how much force is required for a chuck jaw (that is...

    why do my parts often change to a gold color and all of the lines become very thick?

    The parts that do this are imported from SolidWorks, I have attached a screen shot. I am working in NX8 and using the Manufacturing function. The only way I can get it back to the normal color is to switch to Part Navigator and uncheck the model but that means I have to regenerate all toolpaths...

    intersection point of two askew cylinders

    Hello all, I have a family of parts that typically has two cylinders which intersect; I am looking for the point that is farthest from the midpoint of the largest cylinder's axis... The angle between the two cylinders is either 45° or 60° One cylinder, let's call it the main cylinder, is...

    trouble with checking status of events or commands...

    I was following along with John Joyce's PLM World 05 PowerPoint for the probing example... this is what my current procedure looks like: proc PB_CMD_probeXpos {} { global mom_probex_status global mom_probex_pos #if { $mom_probex_status != "ACTIVE" } { return} set probex_pos [ format %3.4f...

    Is it possible to import or open a Solidworks part and still have the Feature Tree?

    Perhaps "Feature Tree" is not the proper terms but that is what my Solidworks instructor called it, geez, that was a long time ago... at any rate I read this while searching this forum for the answer to my question... Is the *.xmt_txt file format only available in SW Pro? I have tried saving...
