Essential Interview Questions For Computer Numerically Controlled Shot Peening Operator
1. Describe the basic principle of shot peening and its benefits?
Shot peening is a metalworking process that involves impacting a metal surface with small spherical beads (called shot) at high velocity. This process creates tiny indentations on the surface, which can improve the fatigue strength, wear resistance, and corrosion resistance of the metal.
- Increases fatigue strength by introducing compressive residual stresses into the surface.
- Enhances wear resistance by creating a hardened surface layer.
- Improves corrosion resistance by sealing surface cracks and pores.
2. Explain the role of each component in a Computer Numerically Controlled (CNC) shot peening machine?
CNC Control System
- Controls the movement of the shot peening nozzle.
- Determines the shot peening parameters (intensity, coverage, etc.).
Shot Peening Nozzle
- Directs the shot stream onto the target surface.
- Can be adjusted for different shot sizes and intensities.
Shot Peening Media
- Spherical beads made of various materials (e.g., steel, ceramic).
- Selected based on the desired surface finish and properties.
3. How do you determine the appropriate shot peening parameters for a given application?
The appropriate shot peening parameters depend on the material, geometry, and desired outcome of the application. Factors to consider include:
- Shot size and material
- Shot intensity (force applied by the shot)
- Coverage (percentage of surface area peened)
- Time and pattern of peening
4. Describe the quality control procedures involved in shot peening?
- Visual inspection of the peened surface for uniform coverage and no defects.
- Hardness testing to verify the desired surface hardness.
- Residual stress measurement to ensure the introduction of compressive stresses.
- Fatigue testing to assess the improvement in fatigue life.
5. How do you troubleshoot common problems that may arise during CNC shot peening?
- Incorrect shot peening parameters (adjust parameters based on application requirements).
- Clogged shot peening nozzle (clean or replace the nozzle).
- Insufficient shot flow (check shot supply and refill if necessary).
- CNC control system errors (refer to manufacturer’s manuals for troubleshooting).
6. What safety precautions should be followed when operating a CNC shot peening machine?
- Wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and earplugs.
- Ensure the machine is properly grounded and secured.
- Keep the work area clean and free of debris.
- Never operate the machine without proper training and authorization.
7. Describe your experience in programming and operating CNC shot peening machines?
