In a planer
  • a)
    tool is stationary and work reciprocates
  • b)
    work is stationary and tool reciprocates
  • c)
    tool moves over stationary work
  • d)
    tool moves over reciprocating work
Correct answer is option 'A'. Can you explain this answer?

The correct answer is b.
On the planer the work is moved against a stationary tool: on the shaper the tool moves across the work, which is stationary. On the planer the tool is fed into the work; on the shaper the work is usually fed across the tool. The drive on the planer table is either by gears or by hydraulic means.

- Explanation:

Stationary Tool and Reciprocating Work:
In a planer, the tool is stationary while the workpiece reciprocates back and forth underneath the tool. This means that the cutting tool remains fixed in position while the workpiece is moved in a linear motion.

How it Works:
As the workpiece moves back and forth, the stationary tool removes material from the workpiece surface, creating a flat and smooth finish. The tool is designed to make precise cuts at each pass, ensuring accuracy and consistency in the finished product.

Advantages:
- This setup allows for more control over the cutting process, as the tool remains in a fixed position.
- It also enables the creation of large flat surfaces with high precision and accuracy.

Applications:
Planers are commonly used in woodworking and metalworking industries for tasks such as shaping, smoothing, and leveling surfaces. They are particularly useful for creating flat surfaces on large workpieces.

Conclusion:
In summary, in a planer, the tool is stationary while the work reciprocates back and forth. This setup allows for precise cutting, control over the process, and the creation of flat surfaces with high accuracy.
