I have a setup that came to me that I needed to make some changes on that is pretty much a black box. I can't open it to take measurements (more than once or twice) because it is constantly running tests at temp and RH%. No CAD for it. No one knows who made it, just that it came from another...

Hi All, My apologies first off if this is not posted in the correct category. I looked around for a bit and could not find an ideal category to post in. This is quite a specific request, but maybe someone on here w/ more industry knowledge than I will know something off the top of their...

Awesome, thank you all for the help. This problem can now be marked "solved."

Awesome, thank you IR!

Hi, Has anyone used matte black spray paint on a machined metal surface to prevent potential laser specular reflections? Usually I have my aluminum parts used with laser systems Black Type II Anodized to help prevent specular reflections, but I can't do this in this instance due to lead time...

I see, thank you all!

Material is PEEK. I can't post a drawing of my specific part, but here is a pic of what I am talking about. Basically having these four fillets be R0.20 mm.

Excuse my ignorance on this subject, but why does using small radius fillets increase the price of the part for CNC machining? Radius size I am talking about is R0.20-R0.40 mm (R0.008"-R0.015"). The geometry I am talking about is top down vertical milling when removing a rectangular shape from...

Hi, I have some witness lines on some dimensions referencing a number of rounds and fillets. It seems like the Witness Line Offset value in Drawing Properties affects the length of the witness lines displayed. With Rounds scaling proportionally to the offset value and fillets scaling inversely...

Thank you. This makes sense.

If I have a climate chamber - elevated temp and RF%, and have a sheet of transparent acrylic inside. Steady state conditions for both temp and humidity - so acrylic sheet is the same temp as air. Will condensation form on the clear acrylic sheet? I am thinking condensation will not form on...

Hi, I am looking for a low CTE polymer for rapid prototyping. This polymer can be filled (glass, carbon fiber, etc). I need it to have a CTE around 15 ppm/deg C. It also need a glass transition temp, T_g > 100 deg C. I have found Ultem 1010 and Ultem 9085 satisfy the T_g requirement, but...

Hi IRstuff, Apologies for the delayed reply. I am trying to measure the length of the laser projection on the flat acrylic sheet. I found out a subset of one of my company's machine shops has the ability to print directly onto acrylic and was able to print this pattern accurately enough for my...

Hi dgallup, Thank you for this advice. This worked well for me. Have a nice day!

Hi All, This is for Creo 4.0. I feel like this should be a simple task, but I am stuck. I've made a sketch (Model>Datum>Sketch) of a grid of circles on a flat plane. I want to now fill these circles black. Right now they are just empty circles that I have changed the line color to black...

Hi All, Dimensions of the polycarbonate sheet are 270 mm x 380 mm x 6 mm. Purpose of polycarbonate sheet is to serve as a target for a laser pattern (bottom side of sheet is frosted). Camera w/ computer vision application measures the laser pattern. Having the grid printed on the frosted...

@IRstuff So long as the dot grid pattern is accurate to itself to that tolerance then it is sufficient. So the pattern is floating. If it is a square pattern, and d is the distance between each dot, I need the printed distances to be d+/-0.1 mm. If the pattern is accurate to this, but the...

Tolerance of +/- 100 microns. +/- 50 microns if possible.

Hi All, I am trying to print a camera calibration dot grid on a polycarbonate sheet I have. I need this grid to have a high tolerance. I have reached out to a number of places that specialize in printing on acrylic, but all are for photography, portraits, etc., and thus have very poor...
