Hello, I have seen several old posts from 'JohnRBaker (Mechanical)' using 'grip program' to export point data (x,y,z) from NX native file in the form of .dat file thread561-379920 (see attached example). I'm wondering if any of you could please help me modifying the code to export the point...
Thank-you metengr for your input. It clarifies a few things for me.
However from the manufacturer of barstock and incomming quality (for machined products) points of view, what is the difference b/w making barstocks to either standard... are they both not hot or cold rolled products?
I was wondering if I could change Change A479 with A276 for pressure application (for SS316L material)? I have been told that A479 is suited for B&PV application and A276 for structural application. Could some one shed light on this topic?

I am looking for industry accepted tolerances for various manufacturing processes (metals and plastic processing). Are there any industry norms to control these tolerances? The manufacturing processes I am specifically interested are:
Investment Casting
Pressure die casting
Deep drawn metal...
Can bar stock material (per ASME sec. II - say SS316L per ASME A 479) be used to make flanges in pressure vessels per ASME B&PV std.? I have notes in ANSI B16.5 that only Forgings / Castings & Plate Stock is Permitted.
Pl. Comment.
Thank-you in advance for your suggestions.

For manufacture of a custom flange for pressure application I was looking for European equivalence to SS316L plate stock (per ASME A 240). My major concern for the equivalency is chemical composition. Can someone suggest me a European equivalent to SS316L plate stock (per ASME A 240)...
For my process condition (various aggressive chemicals @ -25 deg C / -15 deg F) I have been advised by our marketing dept. to select Perfluoro-elastomer (FFKM) - Kalrez / Equiv. grade suited for the low temperature service (-25 deg C / -15 deg F).
1) Can anyone suggest me a FFKM compound that...
Thank-you All for your feedback. BillPSU you are correct with your assumption that we are doing a circular weld around circumference of the part. The dimension of the bore is 0.339 with tolarence of +/- 0.8 thousandth of an inch. As you have said the welding is dependant on many variables, will...
I need to TIG weld two machined (cylindrical) SS316L parts. Both parts have a identical central bore which has to be perfectly alligned after welding. I have considered using various centering features and clamping options but was unable to get the allignment of the central bore after welding...
Thank-you All,
I have 2 questions I would like to have guidance on:
1) Can anyone pl. suggest and work done on the condensation through a polymeric barrier (say virgin PTFE) by means of Permeation of process fluid (at steam) at elevated pressure and temperature. I am specifically looking for the...
Can anyone pl. suggest and work done on the condensation through a polymeric barrier by means of Permeation of process fluid (at steam) at elevated pressure and temperature. I am specifically looking for the approach to measure and estimate.
cheers,
