5-Axis Machining with FANUC CNC Technology


The Series 30i and Series 31i-5 control systems are designed to simplify complex, high-performance 5-axis machining applications, and use advanced spline interpolation to faithfully recreate the original CAD drawing from the line segment approximations.

The CNC and drive system executes at a nanometer resolution all the way down to the 16,000,000 count encoders for the maximum precision and the smoothest contoured surface finish quality. Parts are produced that match the designer’s intent with faster cycle times and a superior surface finish.

The 5-Axis CAD/CAM/Machine workflow is simplified by creating part programs that describe part geometry and allowing machine, tooling and setup data to be provided at the machine.

5-Axis Machining with FANUC CNCs - Features and Benefits

Simplified 5-Axis CAD/CAM/machine Workflow


By separating the machine, tooling and part setup details from the part geometry the part program that is created is much simpler. This also simplifies the CAM and postprocessor tasks significantly, making them more reliable and less costly. The machine, tooling and part setup details are provided at the machine, similar to the typical 3-axis workflow, using the features described below.

Workpiece Setting Error Compensation


Workpiece Setting Error Compensation (WSEC) resolves the differences between the part coordinate system and the machine coordinate system, compensating for the actual part location and orientation on the machine in 3D.

Tilted Working Plane


Tilted Working Plane (TWP) establishes a temporary coordinate system to simplify the programming of part features on a localized working plane for both 5-axis simultaneous and “3+2” machining.

AI Contour Control


AI Contour Control (AICC) looks ahead in the part program to eliminate acceleration/deceleration and servo delays to provide higher-speed, higher-precision machining with improved part accuracy and quality.

3D Volumetric Error Compensations


3D Volumetric Error Compensations fine tunes the results of mechanical and thermal compensations to achieve the best possible machine accuracy.

Machining Quality Level Adjustment


Machining Quality Level Adjustment (MQLA) provides an intuitive tool for machinists to optimize performance profiles for roughing and finishing by prioritizing between speed, accuracy and surface finish quality.

3D Interference Check


3D Interference Check protects the machine from damage by preventing moving and fixed components colliding.

3D Manual Feed


3D Manual Feed simplifies manual interventions by allowing the operator to retract tools in the tool axis direction and jog perpendicular to or parallel to the working plane.

FANUC 5-axis Technologies 

Workpiece Setting Error Compensation

Workpiece Setting Error Compensation (WSEC) resolves the differences between the part coordinate system and the machine coordinate system, compensating for the actual part location and orientation on the machine in 3D.

High-Speed Smooth TCP

High-Speed Smooth TCP provides Tool Center Point Control (TCP) to allow part geometry programming independent of machine kinematics, and ensures that the tool tip precisely follows the part profile at the programmed feedrate - eliminating the need for special inverse time programming.

Nano Smoothing

Nano Smoothing activates real-time spline interpolation to recreate the smooth curve originally defined by the CAD system from the line segments modeled by the CAM system, improving surface finish and processing speed.

3D Cutter Compensation

3D Cutter Compensation applies tool radius and tool nose compensation in any cutting plane.
