Task 1: Classifying and coding component parts 1. Explain the Opitz method of classifying and coding parts.

Task 2: Processing through group facilities 1. Investigate grouping the parts into a part family that could be manufactured in a flexible manufacturing cell (FMS). Produce a list of the machinery resources that will be required to manufacture the quantities required by the customer.

Task 3: Process planning 1. Use the information in ‘Case study 1’ to produce a list of all the parts contained within the product and indicate whether they are to be manufactured in house or bought in. (Make or Buy decision) 2. For the parts to be manufactured in house draw up process plans for the machinery identified in task 2 to manufacture the parts and indicate the following: · Operation timings · Material required · Machinery/processing equipment · Tooling required · Labour requirements · Quality checking systems to be utilised

Task 4: Production scheduling 1. Use the process planning information from task 1 and the lead time/customer requirements in the ‘Case study 1’ to develop a production schedule that will achieve the customer deadline. 2. Produce a CPA analysis to identify operational activities and bought in component ordering to ensure that there are no bottlenecks in production.

The Opitz method of classifying and coding parts is a systematic approach utilized primarily in manufacturing and engineering to organize parts based on their characteristics, functions, and production requirements. Developed by Friedrich H. Opitz, this method aids in establishing an efficient coding system that facilitates inventory management, procurement, and production planning. This paper aims to explain the principles underpinning the Opitz method, analyze its application in modern manufacturing processes, and examine its benefits and limitations in classifying diverse parts within a production context.

The core principle of the Opitz method involves categorizing parts into identifiable groups using a hierarchical coding system that reflects the parts' functional and geometric attributes. The coding structure typically comprises alphanumeric characters where each segment provides specific information about the part, such as type, material, dimensions, and processability. This systematic classification enables manufacturers to streamline their inventory control, procurement procedures, and production scheduling by providing a uniform way to identify and manage parts across different stages of manufacturing.

One of the primary advantages of the Opitz method is its ability to enhance communication and understanding among various departments involved in the manufacturing process. For example, procurement personnel can quickly identify compatible parts, engineers can recognize standardized components for design purposes, and production teams can streamline assembly and machining operations. The hierarchical structure also allows for easy expansion and modification as new parts are developed or existing parts are updated, maintaining consistency and flexibility within the coding system.

In applying the Opitz method, parts are first analyzed based on their dominant features, such as the type of item (e.g., shaft, bolt, gear), shape, or function. Subsequently, specific attributes like material type, size, and manufacturing process are encoded within the coding structure. For instance, a code might indicate whether a part is metallic or plastic, its dimensions, and whether it requires machining, casting, or standard fabrication. This detailed coding facilitates automated sorting, inventory management, and process planning, ultimately reducing lead times and minimizing errors.

While the Opitz method offers numerous benefits, it also has limitations. Its efficacy depends heavily on the initial analysis and correct assignment of attributes to each part, which requires thorough understanding and consistency. Additionally, for highly complex or bespoke parts, the coding system may become cumbersome, reducing its practicality. Moreover, the method's rigid structure might limit adaptability in rapidly evolving manufacturing environments that favor more agile classification systems.

In contemporary manufacturing contexts, especially with the advent of computer-integrated manufacturing and enterprise resource planning systems, the Opitz method remains relevant as a foundation for developing more advanced classification and coding strategies. Its principles underpin many modern ERP modules that facilitate inventory management and production control. By providing a logical framework for categorizing parts, it helps in automating order processing, bill of materials creation, and manufacturing schedules.

In conclusion, the Opitz method of classifying and coding parts is a valuable tool for enhancing efficiency and organization in manufacturing environments. Its hierarchical structure and systematic approach support inventory management, procurement, and process planning. However, practitioners must be aware of its limitations and adapt the coding system to match the specific needs of their production processes. Integrating the Opitz principles with modern information systems can significantly improve manufacturing agility, accuracy, and overall productivity, offering a robust foundation for current and future manufacturing strategies.
