Study Notes
Operations in Manufacturing
- Loading is composed of picking up a part, placing part in jig, and closing jig
- Operations can be categorized by function into:
- Materials handling and transporting (change in position of the product)
- Processing (change in volume and quality, including assembly and disassembly)
- Packaging (special processing, may be temporary or permanent for shipping)
- Inspecting and testing (comparison to the standard or check of process behavior)
- Storing (time lapses without further operations)
Manufacturing and Production Systems
- Manufacturing processes change the value and quality of materials
- Defective processes produce poor quality or scrap
- Operations performed by machines that do material processing usually add value
- Treatments operate continuously on the workpiece, altering or modifying the product-in-process without tool contact
Design, Materials, and Processes
- The elements of design, materials, and processes are closely related, each affecting the performance of the device and the other elements
- The choice of materials and processes can significantly impact cost
Changing World Competition
- Three major changes in the world of goods manufacturing have taken place:
- Worldwide competition for global products and their manufacture
- High-tech manufacturing or advanced technology
- Efforts to improve the methodology of goods production
Manufacturing System Designs
- Five manufacturing system designs can be identified:
- Job shop (characterized by large varieties of components, general-purpose machines, and a functional layout)
- Flow shop
- Linked-cell shop
- Project shop
- Continuous process (primarily deals with liquids and/or gases)
