Command Architecture & Functional Overview
G70 Finish Turning Contour Cycle is a fundamental CNC programming directive utilized across Fanuc, Siemens, Haas, and Heidenhain controllers for High-speed single-pass finishing cycle executing the exact profile contour defined between P and Q block numbers from G71/G72 cycles..
Syntax Structure & Execution Parameters
- Command Category: Finishing Turning Cycle (Non-Modal Cycle).
- Standard Syntax:
G70 P100 Q200 F0.12. - Operational Function: Executes exact part profile in one smooth pass.
- Critical Safety Rule: Cleans up stepped roughing ridges left by G71, producing mirror surface finishes down to Ra 0.4 μm.
- Production Integration: Tested and standardized across UCAN ROBOT's 150+ high-precision CNC machining centers for zero-collision continuous automated manufacturing.
