HVAX Technologies Limited Interview Questions and Answers

The procedure for wind calculation as per IS code involves determining the design wind speed, selecting the appropriate terrain category, and calculating the wind pressure.

• Determine the design wind speed based on the location and height of the structure.

• Select the appropriate terrain category (rural, urban, etc.) as per IS code guidelines.

• Calculate the wind pressure using the formula provided in the IS code.

• Consider fa...read more

A STAAD model for a fixed pole is a structural analysis and design model used to determine the stability and strength of a pole that is fixed in place.

• In a STAAD model for a fixed pole, the pole is typically modeled as a vertical member with fixed supports at the base.

• The model considers factors such as wind loads, dead loads, and any other relevant loads that may act on the pole.

• The analysis helps in determining the s...read more

Key considerations in designing a square base plate

• Ensure the base plate is large enough to support the load without excessive deflection

• Select appropriate material and thickness to meet structural requirements

• Consider the connection details for attaching the base plate to the structure

• Account for any potential corrosion or environmental factors that may affect the base plate

• Include provisions for anchor bolts or other...read more

CPK is a statistical measure used to assess the capability of a process to produce output within specification limits.

• CPK is calculated using the formula: CPK = (USL - LSL) / (6 * standard deviation)

• A CPK value greater than 1 indicates that the process is capable of producing within specification limits

• A CPK value less than 1 indicates that the process may not be capable of consistently producing within specification l

Ra in roughness tester is the average roughness value of the surface profile within a specified sampling length.

• Ra is a parameter used to quantify the roughness of a surface.

• It is calculated as the arithmetic average of the absolute values of the profile heights over the evaluation length.

• Ra provides a measure of the deviation of the surface profile from the mean line.

• It is commonly used in industries such as manufactu...read more

7QC tools are a set of quality control tools used for process improvement and problem-solving in quality management.

• Check sheets: Used to collect and analyze data in a systematic way.

• Histograms: Used to show frequency distribution of a process.

• Pareto charts: Helps identify the most significant factors contributing to a problem.

• Cause-and-effect diagrams: Used to identify and analyze potential causes of a problem.

• Scatter...read more

The 8D methodology is a problem-solving approach used in quality management to identify, correct, and prevent recurring problems.

• The 8D methodology consists of 8 steps: D0 - Plan, D1 - Team Formation, D2 - Problem Description, D3 - Interim Containment Action, D4 - Root Cause Analysis, D5 - Permanent Corrective Action, D6 - Prevent Recurrence, D7 - Recognize Team Effort, D8 - Closure and Team Disbandment

A CNC machine works by using computer programs to control the movement of the machine's tools and workpiece to create precision parts.

• CNC machines use computer programs to control the movement of the cutting tools and workpiece.

• The programs are created using CAD/CAM software and converted into G-code instructions.

• The machine reads the G-code instructions and moves the tools along the specified paths to cut and shape th...read more
