3. How do you troubleshoot a CNC press brake if it is not bending the material correctly?

• Check the material thickness and ensure it is within the machine’s capacity.
• Check the die and punch for wear or damage.
• Check the machine’s hydraulic pressure and ensure it is within the correct range.
• Check the CNC program and ensure it is correct.
• Tighten any loose bolts or screws on the machine.

4. What is the difference between a hydraulic shear and a mechanical shear?

• Hydraulic shears use hydraulic pressure to cut the material, while mechanical shears use a mechanical force.
• Hydraulic shears are typically more powerful than mechanical shears and can cut thicker materials.
• Hydraulic shears are also more versatile than mechanical shears and can cut a variety of shapes.

5. How do you maintain an ironworker machine to ensure it is operating safely and efficiently?

• Inspect the machine regularly for wear or damage.
• Lubricate the machine according to the manufacturer’s instructions.

• Follow all of the manufacturer’s safety instructions.

7. How do you calculate the correct feed rate for a CNC turret punch?

• Determine the material thickness.
• Determine the punch diameter.
• Refer to the manufacturer’s recommended feed rates for the material and punch diameter.

8. What is the purpose of a stripper in a CNC turret punch?

• To prevent the material from sticking to the punch.
• To help clear the slug from the punch.
• To improve the accuracy and quality of the punched holes.

9. What is the difference between a CNC plasma cutter and a CNC waterjet cutter?

• CNC plasma cutters use a plasma arc to cut the material, while CNC waterjet cutters use a high-pressure water jet.
• CNC plasma cutters are typically faster than CNC waterjet cutters, but CNC waterjet cutters can cut a wider variety of materials.
• CNC plasma cutters can cut thicker materials than CNC waterjet cutters.

10. What is the purpose of a CNC controller?

• To control the movement of the machine’s axes.
• To store and execute the cutting program.
• To monitor the machine’s sensors and alarms.
• To provide feedback to the operator.
