Top 10 Questions for Automatic Profile Shaper Operator Interview

1. Describe the basic principles of operation of an Automatic Profile Shaper?

An Automatic Profile Shaper is a machine tool that uses a rotating cutter to shape the profile of a workpiece. The workpiece is held in a fixture, and the cutter is moved along the desired profile path. The cutter is usually made of carbide or diamond, and the workpiece is usually made of metal or plastic.

• The machine is controlled by a computer, which reads the profile path from a CAD file.
• The computer then generates a series of commands that move the cutter along the path.
• The cutter is rotated at a high speed, and the workpiece is fed into the cutter at a controlled rate.
• The result is a workpiece that has been shaped to the desired profile.

2. What are the different types of Automatic Profile Shapers?

Vertical Profile Shapers

• The cutter is mounted on a vertical spindle.
• The workpiece is held on a table that moves in the X and Y axes.
• This type of shaper is used for shaping flat or slightly curved profiles.

Horizontal Profile Shapers

• The cutter is mounted on a horizontal spindle.
• The workpiece is held on a table that moves in the X and Z axes.
• This type of shaper is used for shaping complex profiles.

3. What are the key factors to consider when selecting an Automatic Profile Shaper?

• The size of the workpiece
• The complexity of the profile
• The desired accuracy
• The budget

4. What are the different types of cutters used in Automatic Profile Shapers?

Single-point cutters

• These cutters have a single cutting edge.
• They are used for shaping simple profiles.

Multi-point cutters

• These cutters have multiple cutting edges.
• They are used for shaping complex profiles.

5. What are the different types of fixtures used in Automatic Profile Shapers?

Mechanical fixtures

• These fixtures use clamps or screws to hold the workpiece in place.
• They are simple to use and inexpensive.

Vacuum fixtures

• These fixtures use a vacuum to hold the workpiece in place.
• They are more expensive than mechanical fixtures, but they can be used to hold workpieces of any shape.

6. What are the different types of controls used in Automatic Profile Shapers?

Manual controls

• These controls allow the operator to manually move the cutter and the workpiece.
• They are simple to use, but they require a skilled operator.

CNC controls

• These controls use a computer to control the movement of the cutter and the workpiece.
• They are more expensive than manual controls, but they can produce more accurate and consistent results.

7. What is the difference between a profile shaper and a milling machine?

• Profile shapers are used to shape the profile of a workpiece.
• Milling machines are used to cut flat surfaces into a workpiece.
• Profile shapers typically have a single cutting edge, while milling machines typically have multiple cutting edges.
• Profile shapers are typically used for low-volume production, while milling machines are typically used for high-volume production.

8. What are the safety precautions that must be taken when operating an Automatic Profile Shaper?

• Wear appropriate safety gear, including safety glasses, gloves, and a dust mask.
• Keep the work area clean and free of debris.
• Make sure the machine is properly grounded.
• Never operate the machine without the guard in place.
• Be aware of the moving parts of the machine.

9. What are the maintenance procedures that must be performed on an Automatic Profile Shaper?

• Clean the machine regularly.
• Lubricate the moving parts regularly.
• Inspect the cutter and the fixture regularly.
• Calibrate the machine regularly.

10. What are the troubleshooting tips for Automatic Profile Shapers?

• If the machine is not cutting properly, the cutter may be dull or damaged.
• If the workpiece is not being held securely, the fixture may be loose.
• If the machine is making excessive noise, the bearings may be worn.
• If the machine is not moving smoothly, the drive belt may be loose or damaged.
