The five axis mold carving and milling machine of Maxus CNC breaks through the limitations of traditional processing equipment in complex mold processing with multi axis linkage technology. The core principle is to construct a spatial cutting trajectory through multi axis collaborative motion, combined with precision control algorithms, to achieve efficient machining of complex curved surfaces and irregular structures of molds.
The foundation of multi axis linkage is the hardware configuration of the five axis motion system. The Maxus five axis engraving and milling machine usually adopts a layout of "X, Y, Z linear axes+A, C rotation axes": the X and Y axes drive the worktable to move in the horizontal plane, and the Z axis controls the spindle to complete vertical feed, forming a three-dimensional linear motion framework; The A-axis (rotating around the X-axis) and C-axis (rotating around the Z-axis) change the relative posture between the tool and the workpiece by driving the workpiece or spindle to deflect. This structural design allows the tool to approach the workpiece from more angles, especially suitable for processing complex structures such as deep cavities and inverted buckles in molds. Each axis is driven by high-precision servo motors, combined with ball screws and linear guides to ensure smooth motion and positioning accuracy, providing hardware support for linkage machining.
The core of implementing complex machining through multi axis linkage lies in coordinate transformation and trajectory planning. When processing 3D curved molds, the tool paths generated by CAD/CAM software need to be converted into motion commands for each axis. The Maxus CNC system decomposes the spatial position and attitude parameters of the tool into X, Y, and Z axis displacements and A and C axis rotation angles through inverse kinematics algorithm. For example, when processing the spherical features of a mold, the system calculates the instantaneous motion parameters of each axis in real time: while maintaining the feed depth of the Z-axis, the A-axis and C-axis rotate in coordination to keep the tool always tangent to the spherical surface, and the X and Y axes drive the workpiece to complete the unfolding motion of the spherical surface. This dynamic coordination ensures that the tool center moves strictly along the theoretical trajectory, avoiding over cutting or under cutting.
Trajectory smoothness control is a key technology for multi axis linkage. The Maxus CNC system uses high-order interpolation algorithms to generate continuous and smooth transition trajectories between discrete programming points, reducing sudden changes in axis motion. At the same time, the system uses dynamic error compensation function to correct motion deviations caused by mechanical clearances and load changes. For example, when machining the corners of molds at high speed, the system automatically adjusts the acceleration of each axis to synchronize the motion transition between the linear axis and the rotating axis, reducing the impact of vibration on machining accuracy. In addition, by setting a reasonable matching relationship between feed rate and spindle speed, the cutting load is ensured to be stable, avoiding surface quality degradation caused by cutting force fluctuations during multi axis linkage.
The multi axis linkage principle of the Maxus five axis mold carving and milling machine is essentially a combination of hardware accuracy and software algorithms to transform the three-dimensional design of complex molds into precise mechanical motion. This technical solution not only leverages the flexibility of multi axis structures, but also ensures machining accuracy through precise control, providing a reliable solution for efficient manufacturing of complex molds.
