how square are the edges to each other & to the bottom & top? at least one end needs to be square. I don't know how square it is now. We can get the squares perfectly milled. what is the volume? this will dictate type of tooling & fixturing. The volume is not an issue. It is a kind of mass...

The workpiece material: Steel #45, similar to JIS S45C, ASTM 1045, 080M46, DIN: C45 Hardness:Normalized, HB220 Job Description: The top & bottom surface have been pre-surface-ground To machine 3 holes from the solid blank only! Hole dia. 50mmH6 Hole dia. 100mmH6 Hole dia. 75mmH6...

I have had a talk with a math professor. He said X = column 1 Y=(Reference diameter/2)*Cos(column 3) Z=(Reference diameter/2)*Sin(column 3) Y value in the column 2 should be the machine movement value in Y-axis. When building the model, the column 2 should not be considered at this stage.

this file was supplied from a designer in Germany. I don't know why there are a few lines on the header. The header should be removed. The file has been revised and re-attached...

It is from my customer.They are very hard to deal.

Wonderful. Can you please convert one assembly file for me? THANKShttp://files.engineering.com/getfile.aspx?folder=b852b845-2aeb-43c9-9b63-5a21c4cbdc01&file=TrackFrame1.SLDASM

Can anyone help to open the file with Solidworks and save the file as IGES or STEP. My NX cannot open the file. Thank you very much for your help.

Thank you, Uwam2ie Unfortunately I don't have ST4 or ST5 available. Can you please upload the file and let me share it after you convert it into NX part file? Thanks

Thank you Frank & Toost, Could you please take a look at this file attached? The quality of the curve is very good. i don't worry about the smoothness of the curve. The reference diameter is 121.5mm The Pin diameter is 40mm I believe that X will be still A from the table Y=(121.5/2)*Cos(A)+(Y...

Thank you for your quick response. I wish to build the model with standard NX built-in capability. But so far not successfully. The only solution found up till now is using journal provided from Frank.

Hi John, Why do you complain about it? You may think it is very basic and simple. But up till now, I have NOT seen any solid idea (solution) from you. It may not be exactly what you think how simple it is. Can you please help to solve the 'BASIC problem' as you called?

How to convert SLDASM file into NX part file? There is always some error when I open the file directly in NX. This file is quite large. It cannot be uploaded here. please download it from my Dropbox.

The follower pin positions are given in TXT file in (X, Y, A). There are two followers in this file. I want to know how to build the two curves around the cylinder. It would be great to have some code to let me select the cylinder size of any size, position and orientation. The quality of the...

Hi Frank, Please find the small plot attached. You can see that the curve is not very smooth. I guess that X-axis decimal places is not enough. http://files.engineering.com/getfile.aspx?folder=5c5bebf3-b9f7-492c-b731-d020d57bc8ef&file=CurvePlot.png

Thank you, Frank. I believe that your method is exactly what I am looking for. At the same time, I am also asking the cam designer to provide me more accurate points, especially for X-axis coordinates. The decimal places for X-axis in the original txt file don’t look enough. The angle value...

Thank you, Frank With your journal, I can import the splines directly from the original txt file. A cylinder can be inserted in. the splines will be wrapped on the cylinder very well. I have been struggling in doing the offsetting the curve in order to create the slot. Can you please tell me...

Hi Frank Step 1: Prepare the txt file into DAT file This is how I did without your journal The original coordinate file was txt file in (X, A). I added one more column for Z value. I put constant value 0 for all Z. I changed the format into DAT file because standard NX only allows me to import...

I took me quite a while to create the solid model with law curve method without running the journal. Now I want to subtract the swept, but not successful. Please help with this. Thanks...

I want to subtract the swept. It always gives me an error message 'Thru face does not intersect path of the tool.' Can anyone kindly help with this problem? Thanks

Smoothness of the curve I think that this cam has some problem in their original design. The curve is not smooth enough. Please find the photo attached. Can the curve be smoothed? Can a pin be inserted into the slot and have the jerk analysed, in order to let the pin run smoothly in the slot...
