What are the basic factors for selecting a material?
Factors affecting the selection of materials:
- (i) Component shape:
- (ii) Dimensional tolerance:
- (iii) Mechanical properties:
- (iv) Fabrication (Manufacturing) requirements:
How do you select materials?
Best Practices for Choosing Materials
- Understand the critical components of your design. The first step in the process of choosing the right material is to understand which structural elements are most important for the mechanical integrity of your product.
- Know your materials.
- Validate your mechanical design.
What determines the chemical or physical properties of a material?
physical property: Any characteristic that can be determined without changing the substance’s chemical identity. chemical property: Any characteristic that can be determined only by changing a substance’s molecular structure.
How the force affects the properties of the materials?
Bond Force determines the elastic modulus (or Young’s modulus) of a material (how stiff a material is). Similarly, stronger bonds will enable a material to withstand higher temperatures before the bonds break and the material melts or softens.
What are the four 4 basic steps in 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 the three criteria that are important in the materials selection process?
Thus in the selection of a material: First, we decide on the requirements of the application. Second, we decide on the possible materials we can use in the application. Third, we decide what changes in the material properties are needed.
What do you need to know about material requirements planning?
Material requirements planning (MRP) is a planning and control system for inventory, production, and scheduling. MRP converts the master schedule of production into a detailed schedule, so that you can purchase raw materials and components. Used mostly in the manufacturing and fabrication industries,…
Which is the most important factor in effective control?
The time factor is very important in reporting. If the reports of performance are delayed then measures to improve it will also be late. An effective control can be exercised only if flow of information both upward and downward is prompt.
What are the external factors that affect inventory control?
There are multiple external factors that may affect inventory control. For example, economic downturns may occur and this is something that you will generally have very little control over. Assessing the economy is a must in order to guard against stock outs or a buildup of excess inventory.
Which is the most important factor in planning?
Planning involves the setting of objectives and then deciding about the appropriate course of action. First of all organizational goals are set and then departmental or sectional objectives are decided. The objectives are the targets for the achievement of which all energies are pooled.
