Physical distribution planning:

If the flow products from a manufacturing facility is to be the subject to the flow, then the flow process is referred to as the physical distribution system. the subjects of physical distribution systems are the finished goods produced by a firm. The reseurces of physical distrubition systems include:

1. The customer

2. The sales and accounting departments ,and warehouses

3. The material handling and transportation equipment required to move the finished product

4. The distributors of the finished product

Assembly analysis:

To integrate assembly design and assembly operation analysis, assembly design models should be translated to an assembly analysis models. There have been some research investigations conducted to integrate product design and analysis. Peak at al40 presented a multi-representation architecture of intension of CAD-CAE integration. As an information intensive mapping between design models to analysis models, a product model-based analysis model is reached and a framework to achieve design-analysis associativity is proposed.

On Machine Inspection (OMI):

In recent years there has been a significant growth in the use of tactile probes as on line inspection systems in CNC machining center applications. Called ''On Machine Inspection'', the probes in these systems are mounted in toolholders, inserted into the machine tool spindle stored inthe tool drum, and handled by hte automatic tool changer in the same way that cutting tool are handled. When the probe is mounted in the spindle, the machine tool is controlled very much like a CMM. sensors in the probe determine when contract has been made with the part surface. Signals from the sensor are transmitted to the controoller that performs the required data processing to interpret an utilize the signals.

Dimensional Measuring Interface Specification (DMIS):

DMIS is a protocol that permits two way communication between CAD and CMMs. Use of DMIS has the following advantages: (1) It allows any CAD systems to communicate with any CMM, (2) it reduces software development cost for CMM and CAD companies because only one translator is required to communicate with DMIS, (3) users have grater choise among CMM suppliers, and (4) user training requirements are reduced.
