RASSP Manufacturing Interface (RASSP-MI) Appnote

3.0 RASSP Manufacturing Interface Usage Scenarios

This Section discusses three major activities supported by the RASSP Manufacturing Interface. These activities are described below:

Each of these three activities are discussed in detail in the following Sections.

3.1 Remote, Facility Specific Producibility Analysis

A PCA designer will first use the Manufacturing Interface once initial PCA component placement has been completed. At this point, the design is converted into a standard representation, thus making it accessible to the core functionality of the Manufacturing Interface. The Producibility Analyzer can then be used to analyze the PCA design with respect to specific production capabilities. The output of this analysis will be producibility issues. These issues may be resolved by either modifying the PCA design, by selecting different production lines, or a combination of the two. If the PCA design is modified during the issue resolution process, the design may again be converted to the standard form and analyzed with the Producibility Analyzer. This process is repeated until no issues remain or it becomes clear that the manufacturing facility is not capable of producing the product within an acceptable amount of time, at an acceptable cost, or with an acceptable degree of quality.

3.2 Capturing Manufacturing Facility Knowledge

The manufacturing engineer uses the Manufacturing Interface for two distinct purposes:

Manufacturing capabilities are captured using the Manufacturing Resource Editor (MRE). Capabilities thus captured serve two purposes. First, they provide PCA manufacturing capability information to the Rule Execution Facility. Second, they provide browsable electronic documentation of the manufacturing facility's equipment and organization. Knowledge regarding specific PCA manufacturing equipment may be captured using the MRE, making it more widely available and ensuring that such knowledge will not be lost due to personnel changes.

3.3 Automation Enabled by Industry Standards

Manufacturing engineers may also use the Manufacturing Interface to generate NC programs and setup sheets for PCA assembly machines. The RASSP-MI enables this kind of automation by providing PCA product data in the GenCAD data format. GenCAD is used by Mitron's CIMBridge suite of manufacturing support tools, which include NC program generators and process planning capabilities. In addition, GenCAD forms the basis of the IPC-2510[IPC97] standard currently in development. Once this standard has been completed, the current GenCAD capability can be updated to comply with IPC-2510, thus increasing the generality of the RASSP-MI's capabilities.
