Classification of broaching motions In which broaching arrangement does the workpiece move past a stationary multi-tooth tool to achieve rapid, continuous production?

Introduction / Context:
Broaching removes material with a multi-tooth tool where each successive tooth removes a small additional chip. Different machine configurations suit internal, external, or surface features and varying production rates.

Given Data / Assumptions:

• Stationary vs moving tool setups.
• Production emphasis on continuous throughput.

Concept / Approach:
In continuous broaching, the broach is held stationary while parts move continuously (often on a conveyor or chain), passing across the tool to machine surfaces at high rates. This contrasts with pull/push broaching where the tool travels through or over stationary work, and with surface broaching where the tool typically traverses the work but not necessarily in a continuous production line.

Step-by-Step Solution:
Identify motion: work moves; tool stationary.Associate with production: continuous transfer of parts → continuous broaching.Therefore, select “continuous broaching”.

Verification / Alternative check:
Automotive lines employ continuous broaching for high throughput on flats, slots, and profiles.

Why Other Options Are Wrong:
Pull/push broaching move the tool, not the work, in discrete strokes; surface broaching describes the feature type rather than the continuous transfer-line method; rotary swaging is a forming process, not broaching.

Common Pitfalls:
Confusing feature type (surface vs internal) with the production mode (continuous); assuming all broaching requires tool motion only.

Final Answer:
continuous broaching
