Hi Hudson,
many thanks for the answer. I will have a look at your attached file and let you know how I get on. I can approximate my spline to arcs.
I have to admit this little problem had me stumped. For once I am happy it is difficult! I have used NX quite a bit now and have seen nothing that...
Hi Hudson,
I have attached an image. I want to wrap the red 'strap' around the extruded spline. I hope that gives you a better idea.
many thanks,

Hi Guys,
I have a solid body part which has a variable edge profile. I drew this as a sketch and extruded it to the required thickness in the model. This works great for engineering production drawings but now I need to make assembly drawings that show the part form which is curved not straight...
Hi Guys,
thanks for the replies...
tripleZ: Parellism/flatness tolerances would not be tight. Volume would not be large, 1000 pieces per month. Non marine environment, general use. Edge radius and thickness flexible. Your reply is very interesting - many thanks. It gives me an insight and...
Hi Alan,
ditto. Use a manual lathe to hold the die and workpiece. Turn the die by hand and very carefully feed the work into it. When you are finished very carefully push against the workpiece and turn the die to remove the workpiece....

Hi Guys,
upon further investigation I have decided to make this part via swiss style machining, it is just about cost effective. It takes around 3 minutes per piece off the bar stock and I use a radius tool for the internal edges. I intend to tumble the parts to put a small radius on the...
Hi guys,
many thanks for all the helpful and useful advice. This has certainly got me thinking and reading about die/coining operations. I am starting to get the idea.
Today I investigated further making the part via more traditional methods as ornerynorsk has just suggested. I think I can...
Hi Oldandconfused,
don't buy Chinese, I have spent a lot of time in India and they use anything and everything apart from Chinese machines.
If you could stretch to 10K I think you might get a reasonable used HAAS machine, not the best but value for money and I have seen their lathes really...
Hi Mike,
excellent, that is exactly what I needed to know. I understand. I will investigate making the part as an investment casting and see what the costs come back like.
Many thanks for your help and advice.
best regards,

Hi Mike,
sorry I missed a dimension, the drawing was more to show what I was doing not specifically to send off for production. I don't think that will effect whether on not a 0.5mm radius can be produced via a coining/die operation inside the slot or whether the part can be made at all...
I...
Hi Guys,
I hope someone can help me with this query. I need to manufacture the attached part (material:2mm thick
316l stainless steel, tolerance +/- 0.2mm).
At the moment during the design and testing phase I laser cut the part and add the internal and
external edge radiuses with a profile...
Hi JohnR,
that is awesome, thanks for sharing. The history of the engine development is really interesting to hear. Someone should write a book about that sort of thing. Good literature in this area is really lacking. Thanks for the insight as to how to create the paper effect. I will give that...
Hi Guys,
I have the same model space mouse. The idea is great but the implementation sucks. The buttons are almost unusable, they are to stiff, to close together and pretty much in all the wrong places. The central paddle works flawlessly though, that is why I still use the device.
Overall the...
Hi JohnR,
how would you create the effect as in the first image above where the parts are sitting on top of the drawings? One of the drawings has a curve in the sheet of paper to make it look more realistic I would imagine, any ideas how to achieve this effect?
many thanks,
JohnFox
