In this age of increasing competition, cost and time to market are two very critical factors that all OEM's must seriously address. PTC's
suite of products allows an efficient flow of digital data between a company and it's vendors. Fully implemented, this is a powerful product development system for taking products from concept to the factory floor.
One step where this system is often broken is in communicating manufacturing information to a machining vendor. It is common to create translated versions of a model (i.e. - IGES, STEP, DXF) and to create fully dimensioned drawings for the sake of a vendor that is not Pro/ENGINEER capable. These practices introduce both unnecessary cost and time. While making 2D drawings is sometimes a necessary step in the process, it is tedious, usually non-value added, and lengthens the cycle. Once a drawing is put on paper or a translated version of the model is made, the intelligence and associativity of the model is lost and the power of Pro/ENGINEER is diminished.
Trulife has developed a system with which customers can eliminate the need to create 2D drawings, and rather embed this information into the native Pro/E model. Below, we discuss some basic techniques that can be used to reduce or eliminate the need for creating 2D drawings when transferring product data to Trulife. We then can open your Pro/E part model in Pro/MANUFACTURING
(Pro/NC) and extract the relevant manufacturing data.
Transferring files by email or FTP site
The method of transferring files can either lead to a lot of confusion or it can be really smooth. By using a zipping utility and the naming convention of XXXXX_rev-$.zip (where XXXXX is the part number and $ is the current Rev of the part inside.) it is plainly clear what part number and rev. is being sent. All subsequent zip files with a new rev part should have the rev incremented appropriately.
The config.pro file must be set up with the correct options to be able to communicate well without a print. Below are some options that we recommend:
Tol_mode - Nominal
Linear_tol_0.xxxx - make applicable
Angular_tol_0.xxxx - make applicable
Tol_display - yes
Pro_unit_sys - if metric, make custom – mm, grams, sec.
Template_solidpart - browse to pick model
Model_tree_start - yes
Start_model_dir - browse to “templates” dir. or correct dir.
Accuracy_lower_bound - .0002
Default_dec_places - use most common ie 3
Sketcher_dec_places - use same as default_dec_places
Embedding information into your Pro/E model
There are several places where part information can be embedded into the model:
Parameters are a great place to include information such as:
- Part Number
- Engineering Contact
Notes can be used to communicate items such as:
- General Company and or Workmanship Notes
- Proprietary Notice
- Finishing Specs (such as anodizing, chem film, etc.)
- Rev History
