Tooling Dims VS. Part Model Dims

[plaidgadjo]

Hello All,


I recently began working for a company that has made a practiceof saving a separate copy (non-parametric) of a part file in the tooling directory. They have done this so they could adjust tooling dimensions to get the actual production part to match the part drawing...


Example: A part drawing calls out a .500 diameter. The actual molded part measures .510.


How are you going about making adjustments to your tooling without effecting the part model drawing dimensions, yet still retaining parameterics? Having (2) separate, unrelated models has proved dangerous (and expensive)!


Any advice greatly appreciated! Thank you!

The Tool Design floating module has a shrinkage feature which can be set to any number.

The shrinkage feature will take care of scaling the model. Additionally, you have some options when you define your reference part in a mold assembly. If you create an external inheritance feature then, in addition to shrinkage, you have the option to alter almost anything in the original part model tree including parameters without altering the original model in any way. The external inheritance feature remains associated to the base part so any changes to it will update the mold assembly as well.<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />

You may try to apply shrinkage rate in the part model, File->Properties->Shrinkage change.
Then you drawing file still relate to part file.
Also, the Ref file in the tooling model still relate to part file.
If you need two different drawings, just pull the "Insert here" button up and down in the model tree, you get two drawings.
