Narayana Health Interview Questions and Answers

I have 3 years of experience programming CMM machines in a manufacturing setting.

• Programmed CMM machines to measure precision components according to engineering drawings

• Utilized CAD/CAM software to create measurement programs

• Performed regular maintenance and calibration of CMM machines to ensure accuracy

I have programmed various CMM machines including Zeiss, Mitutoyo, and Hexagon.

• Programmed Zeiss CMM machines for precision measurements

• Experience with Mitutoyo CMM machines for quality control

• Proficient in programming Hexagon CMM machines for dimensional inspection

Create a program for a given drawing

• Understand the dimensions and specifications of the drawing

• Use CMM software to input the coordinates and measurements

• Verify the program by running simulations and checking for accuracy

CMM alignments are the process of setting up a coordinate measuring machine to ensure accurate measurements.

• CMM alignments involve establishing a reference point on the part being measured

• Aligning the machine's axes with the part's coordinate system

• Calibrating the machine to account for any errors in its measurements

• Ensuring the machine is properly leveled and zeroed before measurements are taken

CMM thumb rule is a general guideline used in Coordinate Measuring Machine (CMM) programming to ensure accurate measurements.

• CMM thumb rule states that the probe should always approach the part from the same direction to maintain consistency in measurements.

• It helps in reducing errors caused by variations in probe approach angles.

• Following CMM thumb rule ensures repeatability and accuracy in measurements.

• For example, always approaching the part from the top left corner for al...read more
