Types of defects in parts and troubleshooting methods

• Types of defects: dimensional inaccuracies, surface imperfections, material flaws, assembly errors

• Troubleshooting methods: conducting inspections, using measurement tools, adjusting manufacturing processes

• Example: Dimensional inaccuracies can be troubleshooted by calibrating machines and tools

Glass filled polymer is a composite material made by mixing glass fibers with a polymer resin, resulting in a stronger and more durable material.

• Glass filled polymers have improved strength, stiffness, and heat resistance compared to regular polymers.

• They are commonly used in automotive parts, electronic housings, and industrial components.

• Examples include glass filled nylon, glass filled polypropylene, and glass filled polyester.

Measuring instruments have a least count that determines the smallest measurement that can be taken.

• Least count is the smallest measurement that can be taken with a measuring instrument

• It is determined by the instrument's precision and accuracy

• For example, a ruler with a least count of 1 mm can measure to the nearest millimeter

• Materials used in the instrument's construction can affect its accuracy and precision

An alloy is a mixture of two or more metals, or a metal combined with another element, to enhance its properties.

• Alloys are created to improve the strength, durability, or other properties of metals.

• Common examples of alloys include steel (iron and carbon), bronze (copper and tin), and brass (copper and zinc).

DFM (Design for Manufacturing) is the process of designing a product to optimize its manufacturability.

• Consider manufacturing processes early in the design phase

• Minimize the number of parts and components

• Design for ease of assembly and disassembly

• Use standard components and materials whenever possible

• Collaborate closely with manufacturing engineers

A diode is a semiconductor device that allows current to flow in one direction only. Breakdown can occur due to excessive voltage or current.

• Diode allows current to flow in one direction due to its PN junction

• Breakdown can occur due to excessive voltage (avalanche breakdown) or excessive current (thermal breakdown)

• Zener diodes are designed to operate in breakdown region for voltage regulation

Thevenin's theorem states that any linear electrical network can be replaced by an equivalent circuit consisting of a single voltage source and a single series resistor.

• The theorem simplifies complex circuits into simpler equivalent circuits for analysis.

• It helps in determining the voltage and current across any component in the network.

• The equivalent Thevenin voltage is the open-circuit voltage at the terminals of the network.

• The equivalent Thevenin resistance is the resista...read more

Capacitors store and release electrical energy in AC/DC circuits.

• Capacitors block DC current while allowing AC current to pass through

• Capacitors store energy in an electric field when connected to a DC circuit

• Capacitors release stored energy in the form of AC current when connected to an AC circuit

Stability analysis in control systems involves assessing the stability of a system's behavior over time.

• Stability analysis is crucial in ensuring that a control system operates predictably and reliably.

• Methods such as root locus, Bode plot, and Nyquist plot are commonly used for stability analysis.

• Stability criteria, such as the Nyquist stability criterion or Routh-Hurwitz criterion, are used to determine system stability.

• Instability in a control system can lead to oscillatio...read more
