MultiAxis

Multiaxis refers to any system, device, or representation that involves movement, measurement, or orientation along more than one axis. The term is used across engineering, manufacturing, robotics, data visualization, and computer graphics to denote multi-dimensional or multi-axial operation.

In manufacturing and CNC machining, a multiaxis machine combines multiple linear and rotary axes to produce complex parts with fewer setups. Common configurations include three linear axes (X, Y, Z) and one or more rotary axes (A, B, C). Four- and five-axis machines enable simultaneous or coordinated tool orientation, allowing access to undercuts and angled surfaces while maintaining precision. Programming typically employs computer-aided manufacturing and toolpath interpolation; constraints include machine kinematics, tool length, and collision avoidance.

In robotics, multiaxis refers to robotic arms or mechanisms with several joints that provide multiple degrees of freedom. Each joint can be viewed as an axis; multi-axes enable precise positioning and orientation of an end effector in three-dimensional space, at the cost of more complex control algorithms and calibration.

In data visualization, multiaxis charts use more than one axis to plot datasets that have different units or scales. A common form is a dual- or triple-axis chart with separate y-axes. While enabling comparison across datasets, multiaxis charts can mislead if scales are not clearly labeled or normalized.

In mathematics and computer graphics, multiaxis rotations describe orientation changes about several axes. Representations such as Euler angles, rotation matrices, or quaternions model these rotations; Euler angles can suffer from gimbal lock, while quaternions provide a robust alternative for smooth interpolation and animation.
