Goel Scientific Glass Work Interview Questions and Answers

OEE can be calculated by multiplying Availability, Performance, and Quality.

• Calculate Availability: (Operating Time - Downtime) / Operating Time

• Calculate Performance: (Ideal Cycle Time * Total Count) / Operating Time

• Calculate Quality: Good Count / Total Count

• Multiply Availability, Performance, and Quality to get OEE

• Example: Availability = (400 - 50) / 400 = 0.875, Performance = (2 * 350) / 400 = 1.75, Quality = 300 / 3

Implemented 5S methodology to improve efficiency and organization in the production line.

• Implemented visual management tools to streamline workflow

• Standardized work processes to reduce variability

• Engaged employees in continuous improvement initiatives

• Reduced waste by optimizing inventory management

• Conducted regular Gemba walks to identify improvement opportunities

Flushing is the process of cleaning out a system by forcing fluid through it, while cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure.

• Flushing involves using a fluid to remove contaminants or debris from a system, such as a hydraulic system or a pipeline.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and collapse, leading t...read more

Materials come in different grades based on their composition, properties, and intended use.

• Materials can be classified into metals, polymers, ceramics, and composites.

• Each material type has different grades based on factors like strength, durability, conductivity, and corrosion resistance.

• Examples include steel grades like 304, 316, and 430, polymer grades like HDPE and PVC, and ceramic grades like alumina and zirconi

Stress is the force applied to a material, while strain is the resulting deformation. Mild steel has a linear stress-strain curve.

• Stress is the force applied to a material per unit area, measured in N/m^2 or Pascals.

• Strain is the resulting deformation of the material, measured as a ratio of the change in length to the original length.

• Mild steel typically has a linear stress-strain curve until it reaches its yield point...read more
