diamondjim, The holes diameters need to be ± 0.0005", and the true position should be to the same precision. What do you suggest? Michael PS it is 4140 steel, not the fictional 41340....

Hi, I need some advice on how to enlarge some current holes in a 41340 steel part. The part is a plate with a series of small hole in, varying from 0.030" through to 0.060". The person who designed it, who is no longer working for us, had the machinist drill the holes using a regular drill...

The original Bearing company fafnir went to timken t0 torrington to RBC, and the database it seems is stuck between companies acording to the engineering representatives i asked. I have Mil spec numbers, which part of the number details the grease code? Is there a database i could compare these...

We are creating a proposal to introduce CFD into our company. We do a lot of work for racing teams and as part of our design consultancy program, they are asking for some flow visualization. Some of the jobs they ask are for individual component modeling, i.e. radiator inlets. We already have...

I am comparing two bearings from different manufacturers, both with the same part number, the only difference is the grease code, one has fs464 the other fs428. I have done all the normal google searches but had no luck. Does anybody know the differnce? or alternatively, does anybody know of a...

Forgive me for being so stupid...

I have received a .dwg file, which i have imported into a solidworks part. It has several long very complicated splines, instead of arcs and straight lines. Is it possible to break this spline up into its individual components, from point to point? Cheers, MJ

I am a mechanical engineer, and have been asked to suggest heat treatment processes for a variety of materials. Is there a good reference guide out there? That gives you tables of required strength, hardness, etc... for each material with the corresponding heat treatment process. From my...

Hi All, When I export a solidworks drawing as a .dxf file. The Arcs and Circles in the solidworks drawing are replaced by a series of small flats following the contour of the line. Is there anything I can do to avoid this problem? Our CNC machines are running Mastercam 8.1 and read the .dxf...

Thanks CorBlimeyLimey, I had actually read that page, but not scrolled to the bottom line. It is version 15 for 2k5 for anyone else reading this. Regards, M-J

Hi All, Does anybody know up to what version of parasolids is compatible with Solidworks? Regards, M-J

Try this.. I think it answers all of your questions. http://www.engineersedge.com/thread_strength/thread_minimum_length_engagement.htm Regards, M-J

Thanks For the help. How would you suggest threading the part without a true thread? I ask as I regularly convert to .dxf for our CNC machines. Regards, M-J

Hi All, I have looked at the Help file and a few of the forum readers websites but can still not find an Answer. So I hope I can not be called lazy after I ask this question? Anyhow? Is there an external thread feature in Solidworks 2k5 01.1? Is it a 3D sketch feature or a Helix/Spiral base...

Hi All, We are designing some support stays, w/ rod ends on each end and have a question about thread design. What radius should you put on an externally threaded part after the thread has been completed to avoid crack propogation? We have a 10/32 thread in this example...(Incidentally the...
