Question 151General Subjects - QMED

The correct answer is D) compound rest. The 60° taper angle is commonly used for work supported by lathe centers, and the compound rest is the most efficient method for machining this type of taper. The compound rest allows the operator to set the angle of the cutting tool to the desired 60° taper, making it the easiest and most straightforward approach compared to the other options, which would require more complex setups or adjustments. The taper attachment and headstock/tailstock set over methods are more suitable for machining tapers with different angles, while the compound rest is specifically designed for quickly and accurately cutting 60° tapers on center-supported workpieces.
