The 60° taper angle machined on work supported by lathe centers is most easily machined by the __________.
• Lathe centers and 60° center holes – how work is normally supported between centers • How each device (taper attachment, tailstock set over, headstock set over, compound rest) is typically used to produce tapers • Which method is best for short, precise angles like a standard 60° point
• Ask yourself: when a shaft is already supported between centers, which control (carriage, compound, tailstock, or headstock) can be moved to quickly cut a 60° point at the end? • Which taper‑producing method is commonly used for short tapers such as center points and chamfers, rather than long gradual tapers? • Think about which method would be inconvenient or impossible once the work is already aligned on centers along the bed of the lathe.
• Identify which methods (A–C) are mainly for long tapers along the workpiece length, not just at the end. • Check which device can be swiveled to an exact angle and used for feeding the cutting tool at that angle. • Verify which method is commonly used in practice for cutting center points, chamfers, and short precision angles on work held between centers.
