7. Explain the different types of cutting fluids used in metalworking and their purposes.

• Water-Based Fluids: Soluble oil and synthetic emulsions; provide cooling, lubrication, and corrosion protection.
• Oil-Based Fluids: Straight, neat oils; offer high lubrication and film strength, but can be less effective for cooling.
• Chemical Fluids: Often synthetic; provide excellent cooling and lubrication, but require special handling and disposal.
• Gas-Assisted Cutting: Using inert gases like nitrogen or argon; enhances cooling and reduces friction.
• Cryogenic Fluids: Liquid nitrogen or carbon dioxide; provide extreme cooling, reducing tool wear and improving surface finish.

8. How do you troubleshoot common problems encountered in metal fabrication?

When troubleshooting common problems in metal fabrication, I follow a systematic approach:

• Identify the Problem: Determine the specific issue and its symptoms.
• Analyze the Process: Review the work instructions, materials used, and equipment settings.
• Inspect the Equipment: Check for any signs of wear, damage, or misalignment.
• Adjust or Repair: Implement corrective actions, such as adjusting parameters, replacing worn parts, or calibrating equipment.
• Test and Verify: Run trial operations to confirm that the problem has been resolved.

9. Describe the importance of maintaining accurate records in metalworking.

Accurate records in metalworking are crucial for:

• Quality Control: Documenting parameters, materials used, and inspection results to ensure compliance with specifications.
• Traceability: Tracking the history of metal components for quality assurance and liability purposes.
• Process Improvement: Identifying areas for optimization by analyzing production data and identifying trends.
• Knowledge Sharing: Preserving technical information and best practices for future reference.
• Regulatory Compliance: Maintaining records as required by industry standards and regulations.
