When a lathe is used for thread cutting, the number of threads per inch producedis determined by the speed relationship between the __________.

🔍 Key Concepts

• Lathe threading mechanism – how motion from the spindle is transmitted to the carriage for cutting threads • Lead screw function – what part’s rotation actually advances the tool at a precise pitch along the work • Difference between feed rod (general feed) and the element used for accurate thread cutting

💭 Think About

• Ask yourself: during thread cutting, which two rotating parts must stay in a fixed speed ratio so that every revolution of the workpiece advances the tool by one thread pitch? • Which shaft directly controls the carriage movement for cutting threads, and which shaft turns the workpiece itself? • Is the feed rod normally used for power feed, threading, or both—and which component is specifically designed for accurate thread pitch?

✅ Before You Answer

• Identify which component turns the workpiece (via the chuck) and which component moves the carriage during threading. • Confirm which shaft is called the lead screw and its primary purpose on an engine lathe. • Verify that the choice you pick directly links the rotation of the workpiece to the linear motion of the cutting tool for precise threads.
