360DigiTMG Interview Questions and Answers

Surface profile refers to the overall shape of a surface, while line profile refers to the cross-sectional shape along a specific line.

• Surface profile describes the general shape and features of a surface, such as flatness, waviness, and roughness.

• Line profile focuses on the cross-sectional shape along a specific line on the surface, providing detailed information about variations in height or depth along that line.

• Surface profile is typically used to assess the overall quali...read more

To find coordinates of PCD circles, use a coordinate measuring machine (CMM) to measure the center points and radii of the circles.

• Use a CMM to measure the center point (X, Y) and radius (R) of each circle.

• Calculate the coordinates of the PCD circles based on the measured center points and radii.

• PCD circles are typically used in engineering for positioning holes or features on a part.

• Example: If the center point of a circle is (2, 3) and the radius is 1, the coordinates of th...read more

Gauge acceptance criteria are the specifications that a part must meet in order to be considered acceptable for use.

• Gauge acceptance criteria are typically based on the part's dimensions, tolerances, and other relevant specifications.

• These criteria are established to ensure that parts meet the required quality standards and will function properly in their intended application.

• For example, a gauge acceptance criteria for a machined part may specify that the part's dimensions m...read more

MSA stands for Measurement System Analysis. It is a study that evaluates the measurement system's reliability, accuracy, and precision.

• MSA helps in identifying the sources of variation in the measurement process.

• It consists of three main aspects: Accuracy, Precision, and Repeatability.

• Examples of MSA tools include Gage R&R (Repeatability and Reproducibility) studies and Bias studies.

Part selection criteria for MSA involves considering factors like part complexity, material, size, and critical features.

• Consider part complexity to ensure accurate measurement

• Select materials that are stable and suitable for measurement equipment

• Size of the part should be within the measurement range of the equipment

• Identify critical features that need to be measured accurately

• Ensure parts are representative of the overall production process

• Consider the measurement method be...read more

Types of layout include process layout, product layout, fixed position layout, and combination layout.

• Process layout: Arranges similar machines or equipment together based on the process they perform.

• Product layout: Organizes equipment in a line according to the sequence of operations required to manufacture a product.

• Fixed position layout: Involves keeping the product stationary while workers, materials, and equipment are moved around it.

• Combination layout: Utilizes a combin...read more

RPS alignment stands for Renishaw Productivity System alignment, a method used to align the probe on a CMM machine.

• RPS alignment is a process used to ensure the probe on a CMM machine is accurately aligned for precise measurements.

• It involves setting up the probe in a specific orientation relative to the machine's axes.

• RPS alignment helps improve the accuracy and repeatability of measurements taken by the CMM.

• It is commonly used in industries such as automotive, aerospace, an...read more
