A plea for help.

[Travis_Buchanan]

I have recieved a file from a customer that I need to make a mold for. It is on the ftp as aaa.zip I have worked on this for 2 days in mcam trying to create and extend surfaces out to the border and keep them smooth with no wrinkles. I also need to smooth the seam down the middle. I have projected curves and made loft surface, I projected points and made splines then loft surface. I have not been able to do what needs to be done here. Can anyone offer any suggestions on how to do this. I also tried to toolpath and let the gap settings flow it on over to the border but that didn't work well either.

Email me the file Travis I will try to take a look today at it.

Thanks Ron, it is on it's way.

Is the part symmetrical?

[MATT Q]

By smoothing out are you meaning the part needs to be flat?

[MATT Q]

Almost looks like a baketball back board.

I dont know if i understand you corectly, when i

get solid mold designs in from from our customers

we have them send parasolid files and when we convert them we bring them in as trimed surfaces

which will put all the mold plates cavies exc.on different levels then we can turn on only the parts we need at that time.this works well but the designer must design using levels ?

[Travis_Buchanan]

No the part does not need to be flat. It is a seat for a chair with teh butt impresion. It is called a saddle seat. All I got is the solid model, no creation geometery.

Travis,

 

I have a surface (sheet body) out to the border that may work for you. It dosen't seem to have wrinkles, I can't upload to the FTP site, so where can I send it ?

I also sent you a file with the solid deleted. I used moldplus to create the parting surfaces. From the time I opened your file up to the time I hit file save was about 20 seconds and 6 clicks of the mouse. If you do this type of work, get moldplus, period.

Here is a screenshot of the finished product. It is not as smooth as I would like it to be but I think it will work. What we do is take several thin sheets of veneer, apply glue, put under pressure in this mold, and microwave to cure the glue, then out comes a piece of curved plywood. We then take to the cnc, vacuum down, then cut-out and bore.

 

I also put the new file up on the ftp it is aaa-2.zip. I am still looking for advice and sugestions. Some has mentioned there are better surface packages such as moldplus and Rinho.

I remember seeing a Solidworks tutorial making a chair seat. It's been a while but I think that they were using a domed feature. I can probably find it if you would like to try that and have acess to Solidworks.

[Travis_Buchanan]

Sorry. Mcam is all I got. I took a solids/surface class from Trevor Bailey when he worked at Barefoot and we did a saddle seat in mcam solids. Hey trev, you still got a copy of that chair seat somewhere?

Travis, Look at the "Solids tutorial" manual, they have a chair seat.

 

It is a Version 8 manual

 

The name of the file is chairwire.mc8
