Metal Turning & Machining - Chevalier Jolys

Essential technical reference on metal turning, representing the third fascicle of a comprehensive collection on mechanical manufacturing technology. Written by A. Chevalier (Technical Professor at the École Normale Nationale d'Apprentissage de Paris) and R. Jolys (Assistant Technical Professor at a training center), this volume serves as a cornerstone reference for mechanics technicians and apprentices. The fascicle presents the historical development and general principles of the lathe and lathe operation, tracing the machine's evolution as a fundamental metalworking tool. Detailed coverage includes turning tool classification, characteristics, materials (high-speed steel and metallic carbide), and their specific applications in various machining operations. Significant emphasis is placed on basic turning operations: facing, boring, conical turning, and work between centers. The publication features comprehensive terminology of principal forms achievable on the lathe, supported by detailed technical drawings. Multiple technical plates illustrate elementary surfaces, helical surfaces, and form surfaces, along with clearances and straight grooves. A complete technical lexicon and bibliography enhance this practical guide, making it an indispensable resource for metalworking professionals. Published by Librairie Delagrave, Paris, 1957.
