The document provides machining program codes for 7 examples of CNC lathe operations. Each example includes tool selection, spindle speed, feed rate and G-code blocks to perform turning, grooving, threading and other operations. The tools include roughing, finishing and drilling tools with specified spindle speeds and feed rates for each process. The G-code blocks define the tool paths and machining cycles for the various features to be cut.
