G12 (clockwise circular pocket) and G13 (counterclockwise circular pocket) are high-efficiency cycles designed for creating circular pockets using a single command. Unlike standard contour programming or CAM-generated paths, G12/G13 automatically handle radial stepovers, spiral interpolation, feed control, chip evacuation paths, ...

G187 Haas Tolerance Control: Ultimate 2025 Guide to Smoothness, Accuracy Modes, Real Machining Behavior & Pro-Level Optimization
cnccodeG187 is one of the most critical Haas machining commands, controlling how aggressively or smoothly the machine blends movements during interpolation. While many programmers ignore it, G187 directly determines surface finish quality, corner accuracy, cycle time, and toolpath smoothness. It ...
G187 High-Speed Tolerance Control: Complete 2025 Haas CNC Guide for Accuracy, Smoothness, and Surface Finish Optimization
cnccodeG187 is one of the most critical yet misunderstood Haas CNC commands. It controls how the machine blends motion between linear and circular passes, directly influencing accuracy, toolpath smoothness, surface finish, and high-speed dynamic behavior. G187 affects how the machine ...
G28.1 / G28.2 Zero Return Diagnostics: Advanced 2025 Guide for CNC Axis Homing, Encoder Recovery, and Overtravel Reset Procedures
cnccodeG28.1 and G28.2 are advanced CNC diagnostic commands used for axis homing, encoder restoration, and recovery after overtravel or power-loss errors. These commands are essential when a machine cannot home normally, when absolute encoders lose reference, or when the machine ...
G187 Tolerance Control: Complete 2025 Haas CNC Guide to Accuracy Modes, Surface Finish, and High-Speed Machining Optimization
cnccodeG187 is the Haas CNC command that controls the machine’s motion smoothing, accuracy level, and corner-rounding behavior during high-speed machining. It functions as a tolerance filter that adjusts how aggressively the control blends linear and circular toolpath segments. By modifying ...
G187 Tolerance Control: Complete 2025 Haas CNC Guide for Surface Quality, Corner Accuracy, and High-Speed Machining Optimization
cnccodeG187 is a Haas-specific command that controls the machine’s accuracy, smoothing behavior, and cornering tolerance. It directly influences how the CNC interprets small linear moves, arcs, and high-speed toolpaths generated by CAM systems. With G187, you can switch between roughing ...
G28.1 / G28.2 Zero Return Diagnostics: Complete 2025 CNC Guide for Axis Homing, Encoder Calibration, and Safe Recovery
cnccodeG28.1 and G28.2 are advanced CNC diagnostic commands used for axis zero-return calibration, encoder synchronization, and safe recovery from axis faults. These commands allow the machine to re-establish its home reference using encoder feedback, grid-shift positions, and servo alignment logic. ...
