Cheat Sheet
- Turret Numbering Conventions -
Understand the ISO 6983 standard for turret numbering to quickly recall tool positions: T1 for the first tool pocket, T2 for the second, and so on. A simple mnemonic, "Time To Turn," helps remember indexing order. This is essential for any turret numbering quiz or cnc machining quiz to ensure you load the right tool each time.
- Absolute vs. Incremental Programming (G90/G91) -
Master the distinction between G90 (absolute programming) and G91 (incremental programming) with a sample: G90 X50 Y25 moves to coordinates X50, Y25 from the program zero, while G91 X10 Y5 moves 10 units in X and 5 in Y from the current position. Knowing which mode you're in is a common focus in absolute programming questions. Remember "A then I" (Absolute first, Incremental inside) to avoid missteps.
- Spindle Speed & Feedrate Formulas -
Calculate RPM using the formula RPM = (SFM × 3.82)/D, where SFM is Surface Feet per Minute and D is tool diameter in inches. Then derive feed rate (IPM) by multiplying RPM by the number of teeth and chip load per tooth. These formulas are staples in any cnc test or cnc machine programming test for optimizing surface finish and tool life.
- Coolant Codes and Best Practices -
Use M08 for flood coolant, M07 for mist, and M09 to turn coolant off - key entries in a cnc programming quiz. Select the right coolant type (water-soluble or oil-based) based on material thermal conductivity, as recommended by SME guidelines. A quick tip: "Zero Nine Stops the Shine" helps you recall M09 stops all coolant functions.
- Work Offsets & Tool Length Offsets -
Familiarize yourself with G54 - G59 work coordinate systems to program multiple fixtures in one setup. Input tool length offsets via H codes and confirm with a tool probe measurement routine, as outlined by university-level manufacturing courses. The phrase "Five Four Saves Floor" can remind you that G54 is often the primary offset for part zero.
