Command Architecture & Functional Overview
G71 Rough Turning Outer Diameter Stock Removal is a fundamental CNC programming directive utilized across Fanuc, Siemens, Haas, and Heidenhain controllers for Automated longitudinal turning canned cycle removing roughing stock in parallel Z-passes defined by a profile subroutine (P to Q)..
Syntax Structure & Execution Parameters
- Command Category: OD/ID Rough Turning Cycle (Non-Modal 2-Line Cycle).
- Standard Syntax:
G71 U2.0 R0.5 / G71 P100 Q200 U0.4 W0.1 F0.25. - Operational Function: Generates multi-pass roughing passes automatically.
- Critical Safety Rule: Leaves uniform finishing allowance (U on X, W on Z) for high-speed finishing via G70.
- Production Integration: Tested and standardized across UCAN ROBOT's 150+ high-precision CNC machining centers for zero-collision continuous automated manufacturing.
