01. Dei max and Die min, ISO 4156, are calculated for Tolerance Class 7, regardless of Spline Tolerance Class. Why is this and how is correct ? In one of their Example, they have an Internal Spline Class 5H but Dei max is calculated for 7 class. 02. Involute(X) = 0.03565158 What Formula is used...

Having a Bearing like 35 x 62 x 14 with internal clearance about 0.012 how can I make a relation to Press Fit TOLERANCE on ID How much press fit is too much ? to kill the internal clearance ... That is not my goal at all but the press fit can be calculate with relation to internal clearance ?

NX 9. I have generated (PostProcess) the G-code for a simple milling part. How can I see the relation between any "G code line" and tool path ?

I have a Spline/Curve, from point A to B. I want the Offset to be : 1 mm in A and 2 mm in B

Can NX 9, automatic generate CNC G code from 3D math data ? If not, are there any software who can do this ?

What is the difference between installing a bearing on : - Housing Steel shoulder (bearing outer ring touch the housing shoulder) - Steel washer (between housing and bearing is a washer) If Housing is aluminum, I may understand, to prevent the wearing, but if housing is steel, what would be the...

My Rotor spin to 18,000 RPM max and Shaft is on 2 deep groove ball bearings, about this size, 30-35 x 62-72 x 12-17 The issue I have at high RPM is Vibration. What is the best practice to prevent this ?

Is this possible in Sketch ? Example : p10=2 if p3<100 and p4>2

Looking for an Open Deep Groove Ball Bearing, ID = 35 mm which goes to 20,000 RPM Hybrid ceramic would be an option but I can not find an Open one !

I have a hole on a surface, positioned Point on to point (concentric) with oher hole. I deleted the old position parameter and I want to reposition it again. I can not pick the TOOL Edge at all !!! What is the trik here ?

I have a Shaft on 2 SKF bearings (6005 - Dia25/Dia47/12 and 6207 - Dia35/Dia72/17). Shaft is driven by a dyne at max speed 12,000 rpm. How to calculate the passage oil diameter (in housing) and the oil flow (l/min) for a correct lubrication of bearings ? Oil used is ATF.

I have a very complicated cable shape in Unigraphics NX5 The shape (solid body) is unparametric (imported from parasolid). Is there any way I can recreate the original center spline of cable ?

Attached is a picture. How to bend a bar along an arbitrary line ( in picture is the VERTICAL line) ? so not the line normal to edges ! Thanks

I developed a spline in Sketch and then Swept a profile along that spline. While in Sketch I am using ANIMATE dimenssion, can I see a live update of 3D Swept and record it so I can show it in an external UG enviroment ?

I HOPE sameone here could help me. I have to design a stator winding. Consider a BAR (section 6mm x 1mm). I have to bend this bar, I mean to Sweep (along a guide) and Twist (normal to guide). I was using Swept and Mash Surface with bad results (section I got is not constant along the guide and...

Hello, Could somebody indicate a very good and practical book for designing bevel gears ? Also,as a beginner,as I am,could you please indicate the principal issues in designing the bevel gears ?
