Final answer:
In a lathe machine, the workpiece is typically clamped in the chuck and supported by the tailstock. The chuck holds one end of the workpiece at the headstock, while the tailstock supports the other end with a center or may hold tools for drilling operations. Correct clamping is crucial for precision and safety.
Step-by-step explanation:
In a lathe machine, the workpiece is typically clamped in the lathe's chuck and tailstock. The chuck is part of the headstock and is responsible for holding one end of the workpiece securely during machining operations. Meanwhile, the tailstock is positioned on the opposite end of the lathe bed and can be adjusted towards or away from the headstock to accommodate various lengths of material. The tailstock often has a center that supports the other end of the workpiece, especially when the operation involves long or slender pieces that require additional support to prevent deflection during machining.
Tools such as drill bits or reamers may also be secured in the tailstock to perform drilling operations. Clamping the workpiece and tools correctly is critical for precision in turning operations and to ensure the safety and accuracy of the machining process.
In more advanced or Computer Numerical Control (CNC) lathes, the tailstock may be replaced or supplemented by additional fixtures or centers that provide greater flexibility and precision for complex machining tasks.
