Difficulty: Easy
Correct Answer: all of these
Explanation:
Introduction / Context:
A shaper produces flat surfaces by a reciprocating single-point tool. By selecting tool geometry, clapper box angle, and table/swivel adjustments, the same machine can generate horizontal, vertical, and angular planes. This versatility makes shapers useful for toolrooms and maintenance work despite slower productivity than milling.
Given Data / Assumptions:
Concept / Approach:
Surface orientation follows relative motion between tool and work. With the work clamped at various angles or by tilting the tool head, one can sweep straight-line paths to form horizontal, vertical, and angular faces. Step-over feeds and multiple passes create the required plane size and finish.
Step-by-Step Solution:
Verification / Alternative check:
Typical machine manuals list examples of all three surface types produced on shapers, including V-block sides, angular slides, and guideways.
Why Other Options Are Wrong:
Limiting shapers to a single orientation ignores the adjustability of tool head and work holding; keyways are a niche case and not the only application.
Common Pitfalls:
Poor clamping leads to chatter; incorrect clapper box setting can rub the return stroke; insufficient step-over planning leaves ridges on the surface.
Final Answer:
