What are the factors to be considered in the selection of materials for a machine element?
The following factors should be considered while selecting the material:
- Availability of the materials.
- Suitability of the materials for the working conditions in service.
- The cost of the materials.
What is the material index?
Material index is another term used for the performance index; it is defined by a material property or a combination of material properties in a materials selection process.
What is the relationship between design and material selection?
The selection of the best material for a particular design is intimately associated with the decisions of how to process the material or manufacture a part. This article describes the basic characteristics of manufacturing processes such as material factors, shape factors, and process factors.
What is the relationship of methods and materials?
The materials and methods outline WHAT WAS DONE and HOW IT WAS DONE. There should be enough detail so that someone else could repeat your study. It should be arranged in a logical manner (i.e., keep related ideas together and write chronologically where possible).
How do you select materials for design?
There are several steps to the material selection process….The materials selection process for a component or joint between components involves these steps:
- Identify the design requirements.
- Identify the materials selection criteria.
- Identify candidate materials.
- Evaluate candidate materials.
- Select materials.
What are important criteria for process selection?
Selection of a process depends on the application need. The criteria for selecting a process depend on the production rate, cost, strength, and size and shape requirements of the part, as described below. Depending on the application and market needs, the rate of production is different.
What type of process selection is?
a) Process selection refers to deciding on the way production of goods or services will be organized. Processes convert inputs to outputs; they are the core of operations management. a) Process Selection affects the entire organization and its ability to achieve its mission, and affects the organization’s supply chain.
What are the selection criteria for steel?
Three primary criteria for selecting bar steels are 1) suitability for end use, 2) suitability for manufacturing process, 3) economical delivery of the requirements. Shape can be an important selection factor.
Why we need to automated the process planning?
A completely automated process planning system would eliminate all human effort between the preparation of an engineering drawing and a complete process plan for every manufacturing operation. A less automated system is shown in Fig. 6.9 (b). This system needs human assistance to code the engineering drawing data.
What are the major functions of process planning?
Process Planning has the following important functions: To determine the basic manufacturing process. To determine the sequence of operations. To determine the equipment’s and tooling required.
What is automated process planning?
Automation of process planning is developing via administrative support, the group technology supported variant systems and the generative system possibly supported by the use of artificial intelligence in expert systems.
What is CAPP system?
From Wikipedia, the free encyclopedia. Computer-aided process planning (CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing. CAPP is the link between CAD and CAM in that it provides for the planning of the process to be used in producing a designed part.
What are the advantages of CAPP?
16.11. 4 Benefits of computer-aided process planning 3. CAPP can give faster response to engineering changes. Greater process plan consistency is ensured. Easy access to up-to-date information in a central database can be made available.
What is the full form of CAQC?
The use of the computers for quality control of the product is called as the computer aided quality control or CAQC. The two major parts of computer aided quality control are computer aided inspection (CAI) and computer aided testing (CAT).
Which two disciplines are tied by a common database?
Which two disciplines are tied by a common database? Explanation: Because of their joint benefits, computer- aided design and computer-aided manufacturing are often combined into CAD/ CAM systems.
What is inspection in quality control?
Quality inspection are measures aimed at checking, measuring, or testing of one or more product characteristics and to relate the results to the requirements to confirm compliance. This task is usually performed by specialized personnel and does not fall within the responsibility of production workers.
What is meant by computer aided quality control?
Computer-aided quality assurance (CAQ) is the engineering application of computers and computer-controlled machines for the definition and inspection of the quality of products. This includes: Measuring equipment management. Goods inward inspection. Vendor rating.
What are the disadvantages of computer aided manufacturing?
Computer aided manufacture (CAM)
| Advantages of CAM | Disadvantages of CAM |
|---|---|
| Fast and accurate production | Expensive to set up |
| Machines can run constantly on repetitive tasks | Needs a skilled workforce of engineers |
What is computer aided inspection?
Computer-aided inspection (CAI) is the use of software tools to assess manufactured objects. Its primary purpose is to allow engineers to more quickly and precisely assess the physical properties of manufactured objects. These properties can include dimensions, material consistency, roughness and roundness.
What are 3 disadvantages of CAM?
Disadvantages of CAM
- Computer errors are possible.
- CAD and CAM software can be expensive.
- Training is expensive.
- Computers and controllers to run the software and CNC machinery for manufacturing is expensive.
