Explanation:

  • Tool Wear: In EDM, the tool wear occurs due to the repetitive spark discharge between the tool and the workpiece. This discharge causes the tool to heat up and erode, leading to wear and tear of the tool.

  • Parameters: The tool wear is affected by various parameters such as current, pulse duration, polarity, and tool material.

  • Tool Material: The tool material plays a crucial role in determining the tool wear in EDM. The tool material should have high thermal conductivity and specific heat to reduce tool wear.

  • Thermal Conductivity: The thermal conductivity of a material determines its ability to conduct heat. A material with high thermal conductivity can transfer heat quickly, preventing the tool from overheating and reducing tool wear.

  • Specific Heat: The specific heat of a material determines its ability to absorb heat. A material with high specific heat can absorb more heat, preventing the tool from overheating and reducing tool wear.

  • Option A: The correct answer is option A because a tool material with high thermal conductivity and specific heat can transfer and absorb heat quickly, respectively, reducing the tool wear.

  • Option B: A tool material with low specific heat can lead to rapid overheating and increased tool wear.

  • Option C: A tool material with low thermal conductivity can lead to slow heat transfer, causing the tool to overheat and wear out quickly.

  • Option D: A tool material with low thermal conductivity and high specific heat can lead to slow heat transfer and rapid overheating, causing increased tool wear.
