TCS Interview Questions and Answers

The best simulation of shrinkage in thermal expansion of casting is achieved through finite element analysis (FEA).

• Finite Element Analysis (FEA) is commonly used to simulate shrinkage in thermal expansion of casting.

• FEA software allows for accurate prediction of shrinkage and deformation during the casting process.

• By inputting material properties, boundary conditions, and thermal gradients, FEA can provide valuable insights into the casting process.

• Examples of FEA software co...read more

To increase molten metal pressure in casting area, adjust the pouring rate, increase the height of the pouring basin, and use a pressurized system.

• Adjust the pouring rate to control the flow of molten metal into the casting area.

• Increase the height of the pouring basin to create more pressure when the metal is poured.

• Use a pressurized system such as a vacuum or pressure casting method to increase the pressure of the molten metal.

Thermal expansion affects PDC and press tool manufacturing due to Young's modulus.

• Thermal expansion can cause dimensional changes in materials during manufacturing processes.

• Young's modulus is a measure of a material's stiffness and resistance to deformation.

• PDC (Polycrystalline Diamond Compact) is a material commonly used in cutting tools due to its hardness and wear resistance.

• Press tools are used in metal forming processes and must be designed to account for thermal expans...read more

To correct casting thickness within a model, adjust the design parameters and re-run simulations.

• Modify the CAD model to adjust the thickness of the casting.

• Update the material properties and casting parameters in the simulation software.

• Run simulations to analyze the effects of the changes on the casting quality.

• Iterate the process until the desired casting thickness is achieved.

• Consult with design engineers and casting experts for guidance.

To change trim line within a process, you need to adjust the setpoint of the control system.

• Access the control system interface

• Locate the trim line parameter

• Adjust the setpoint to change the trim line

• Monitor the process to ensure the trim line is functioning correctly

Flow rate can be calculated by dividing the volume of fluid passing through a pipe or channel by the time it takes to pass.

• Flow rate = Volume / Time

• Units of flow rate are typically liters per minute (L/min) or cubic meters per second (m^3/s)

• Flow rate can be measured using flow meters or calculated based on known parameters such as pipe diameter and fluid velocity
