Step 1
Sample checking of finished product for dimensional accuracy
Answer
This method involves evaluating the dimensions of the finished product to ensure they meet specified tolerances. It typically includes the use of calipers and other measuring tools to verify the size and shape against design specifications. Any deviation from the required dimensions may indicate potential issues in the manufacturing process.
Step 2
Mechanical testing for material properties of hardness and toughness
Answer
Mechanical testing focuses on assessing the physical properties of materials used in the product. This includes conducting tests for hardness (e.g., Rockwell or Brinell tests) and toughness (using Charpy or Izod tests). These tests help ensure that the materials can withstand the required operational loads and conditions during the product's lifecycle.
