• Flowcharts - used to show th...read more

Why-Why analysis is a problem-solving technique used to identify the root cause of a problem by asking 'why' multiple times.

• Helps to identify the underlying cause of a problem

• Uses a series of 'why' questions to drill down to the root cause

• Prevents treating symptoms instead of the actual problem

• Improves the effectiveness of corrective actions

• Example: Why did the machine stop working? - Because the motor burned out. Why did the motor burn out? - Because it overheated. Why did i...read more

MSA stands for Measurement System Analysis. It is a statistical method used to determine the variation in measurement data.

• MSA is used to evaluate the reliability and accuracy of a measurement system.

• It helps to identify the sources of variation in the measurement process.

• MSA is important in ensuring that the measurement system is capable of producing accurate and consistent results.

• Examples of measurement systems include scales, gauges, and thermometers.

• MSA involves analyzin...read more

CP is a measure of process capability, while CPK is a measure of process capability with respect to the specification limits.

• CP measures the variability of the process relative to the tolerance range

• CPK measures the capability of the process to produce within the specification limits

• CPK takes into account the deviation of the process from the target value

• CPK is a more comprehensive measure of process capability than CP

5S is a workplace organization method that uses a set of tools to create and maintain an organized, clean, and efficient work environment.

• Sort - eliminate unnecessary items

• Set in order - organize remaining items

• Shine - clean and inspect work area

• Standardize - establish procedures for maintaining the first three S's

• Sustain - ensure the first four S's are maintained over time

• Example: labeling tools and equipment, color-coding materials, creating visual controls

• Example: using ch...read more

Polymer percentage can be checked using techniques like thermogravimetric analysis, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy.

• Use thermogravimetric analysis to measure the change in weight of a sample as it is heated, allowing for calculation of polymer percentage based on weight loss.

• Utilize Fourier transform infrared spectroscopy to analyze the chemical bonds present in a sample, providing information on the types of polymers prese...read more

The ESIC percentage change date is not specified in the question.

• The question is incomplete and lacks necessary information.

• Without a specific date, it is impossible to provide an accurate answer.

A double action press or tool is a machine that performs two actions in one stroke.

• It can cut and bend metal sheets simultaneously.

• It is commonly used in the automotive industry for stamping car parts.

• The press has two rams that move in opposite directions to perform the two actions.

• It is more efficient and saves time compared to using separate machines for each action.

Coil gape can be checked using a feeler gauge to measure the distance between the coils.

• Use a feeler gauge to measure the gap between the coils

• Ensure the coil is at room temperature before measuring

• Check for any irregularities or inconsistencies in the coil gape

Core hardness can be checked using various methods such as Rockwell hardness test, Brinell hardness test, and Vickers hardness test.

• Use Rockwell hardness test for quick and easy measurement
