The document provides 5 CNC machining programs with part sketches, dimensions, tool details, and G-code simulations for: 1) Drilling operations on two different parts 2) Drilling and boring operations on a part with multiple holes and pockets 3) Drilling, boring, and milling operations on a part with complex geometry 4) Drilling, counter-sinking, and milling operations on a part with angled features 5) Drilling, tapping, and milling operations on a part requiring different sized taps The programs include G-code for absolute and incremental modes to simulate the operations using CADEM software.
