PARAMETRIC FIGURE 8 OIL GROOVE TURNING CYCLE

PARAMETRIC FIGURE 8 OIL GROOVE TURNING CYCLE

Professional Internal Figure-8 Oil Grooving From Simple Editable Parameters

Turn complex internal crossed oil-groove programming into a reusable parametric CNC lathe cycle.

The Parametric Figure 8 Oil Groove Turning Cycle uses synchronized X/Z machining to generate two controlled internal groove paths at different spindle phases, producing the characteristic Figure-8 lubrication pattern inside a bore.

Define the bore. Define the groove. Run the cycle. Reuse it for the next job.

🔩 MACHINING STRATEGY

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

1 — FIRST FIGURE-8 GROOVE PATH

The tool begins at the calculated internal starting diameter. Synchronized X/Z passes progressively machine the first groove path through the programmed bore length while increasing the groove diameter in controlled increments.

2 — SECOND 180° GROOVE PATH

Once the first path is complete, the cycle resets and generates the second synchronized path from a 180° spindle phase. The second path crosses the first to produce the complete internal Figure-8 lubrication groove.

FIRST PATH → PROGRESSIVE X CUTTING → RESET → 180° PATH → COMPLETE FIGURE-8 GROOVE

💡 WHY USE THIS CYCLE?

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Different bore diameter? Change the diameter.

Different groove length? Change the length.

Different final groove depth? Change the final groove diameter.

Want finer progressive machining? Change the X increment.

Different machining conditions? Change the spindle RPM.

The Figure-8 machining strategy stays inside the cycle.

Less repetitive programming. Faster setup. Reusable CNC automation.
