Z0, Z1, Z2 Parameters

📐 Z0, Z1, Z2 Parameters in CNC

🔹Z0 – Maximum Tool Lift Height

This is the maximum height the tool can lift from the panel surface when changing tools or moving far away from the material.

👉 If Z1 is set higher than Z0, the software will automatically use Z0 as the upper limit.

📌 Typical value: Z0 = 40mm

---

🔹 Z1 – Tool Lift Height Between Operations

The height the tool lifts between operations when using the same tool (no tool change).

👉 It should be lower than Z0 to reduce up/down travel time and optimize the cutting cycle.

📌 Recommended: Z1 = 5–10mm

---

🔹 Z2 - Cutting Depth Relative to Machine Surface

This is the depth the tool plunges down to cut through the material, measured from the CNC table surface.

👉 Commonly used for edge cuts, through cuts, or internal contour cutting

📌 Typical setting: Z2 = -T - 0.1 ~ -0.2mm Where T is the panel thickness, to ensure a clean cut through the material

⚙ Cutting Speed Parameters

⚠️Notes

• Slow Cutting Speed:

  • This is used for the final edge cut of a part, and must be slower to prevent panel - kickback.

  • 📌 Typically: 1000–2000 RPM

• Maximum Cutting Depth per Pass:

If your panel is 25mm thick and you want to cut in 2 passes, set the max depth per pass to 18mm or 20mm. The machine will then automatically make 2 passes to complete the cut.
