Difficulty: Easy
Correct Answer: Broaching
Explanation:
Introduction / Context:Broaching is a high-productivity machining process in manufacturing where a toothed tool (the broach) is either pushed or pulled across a workpiece. It is used to produce precise internal and external profiles such as keyways, splines, hex holes, and noncircular shapes in one continuous stroke.
Given Data / Assumptions:
Concept / Approach:Each successive tooth on a broach removes a small additional layer of material. The combination of roughing, semi-finishing, and finishing teeth in one tool yields tight tolerances and excellent surface finish without multiple setups.
Step-by-Step Solution:
Identify processes that use push/pull motion with a multi-tooth tool → broaching.Confirm that milling (up/down) uses a rotating cutter, not a push/pull stroke → eliminate.Forming generally plastically deforms metal rather than chips it away → eliminate.Therefore, the correct answer is broaching.Verification / Alternative check:Common broaching applications include internal keyways and splines formed in a single stroke, confirming the push/pull nature and multi-tooth action.
Why Other Options Are Wrong:
Up/Down milling: chip removal by a rotating cutter; not a single linear push/pull stroke.Forming: plastic deformation, no chip removal.Slotting: reciprocating single-point cutting, not multi-tooth progressive tool.
Common Pitfalls:Confusing broaching with slotting or shaping due to the linear motion; the defining difference is the multi-tooth progressive geometry.
