arch cushion skiving machine operator Interview Questions and Answers

1. What is skiving?

   • Answer: Skiving is a machining process that uses a sharp blade to shave thin layers of material from a workpiece, creating a tapered or beveled edge. In the context of arch cushions, it's used to create the specific shape and thickness needed for comfortable fitting and function.

2. Describe the different types of arch cushion skiving machines you are familiar with.

   • Answer: I'm familiar with [List specific types, e.g., rotary skiving machines, reciprocating skiving machines, CNC-controlled skiving machines]. I understand their respective strengths and weaknesses in terms of speed, precision, and material handling.

3. Explain the setup process for an arch cushion skiving machine.

   • Answer: The setup involves carefully aligning the cutting blade, setting the depth and angle of cut, securing the arch cushion workpiece, and programming the machine (if CNC) according to the specifications. This includes checking blade sharpness, feed rate, and the overall machine's operational parameters to ensure precision and safety.

4. How do you ensure the quality of the skived arch cushions?

   • Answer: Quality control involves regular checks of the skiving process, including monitoring the thickness and uniformity of the skived edge, inspecting for defects like tears or uneven cuts, and comparing the finished product against specifications. Regular blade maintenance and calibration of the machine are crucial.

5. What safety precautions do you take while operating an arch cushion skiving machine?

   • Answer: Safety is paramount. I always wear appropriate personal protective equipment (PPE) including safety glasses, gloves, and hearing protection. I ensure the machine is properly guarded, the work area is clean and free from obstructions, and I follow all lockout/tagout procedures during maintenance.

6. How do you handle different types of arch cushion materials?

   • Answer: Different materials (e.g., foam, leather, fabric) require adjustments to the skiving machine settings. For example, softer materials might require slower feed rates and shallower cuts to prevent tearing, while harder materials might need sharper blades and potentially different cutting angles.

7. What are the common problems encountered while operating an arch cushion skiving machine?

   • Answer: Common problems include blade dullness leading to uneven cuts, improper machine setup resulting in inaccurate skiving, material defects causing tears or breaks, and machine malfunctions requiring maintenance or repair. I am capable of troubleshooting these issues based on their symptoms.

8. How do you maintain and clean the arch cushion skiving machine?

   • Answer: Regular cleaning involves removing debris and chips from the machine, lubricating moving parts as per the manufacturer's instructions, and inspecting the blades for wear and tear. Preventive maintenance includes regularly checking and tightening bolts, replacing worn parts, and ensuring proper lubrication.

9. How do you troubleshoot a jammed arch cushion skiving machine?

   • Answer: I would first turn off and lock out the machine. Then, I would carefully identify the cause of the jam (e.g., material buildup, a foreign object). After addressing the cause, I would inspect the machine for any damage before restarting it and resuming operation.
