Global toolpath modulation-based contour error pre-compensation for multi-axis CNC machining

Yang Liu et al.

Summary: This paper proposes a global toolpath modulation-based contour error pre-compensation method for five-axis CNC machining. By incorporating the error compensation issue into the toolpath planning stage, a linear analytical solution is provided to solve the problem of insufficient accuracy in processing parts with tight curvature feature. The method utilizes dual B-spline curves to represent the nominal toolpaths and builds an error model for each individual drive. The satisfaction condition of the spline control points is obtained to eliminate the contour error, and the neighbor-dependent coupling issue in error compensation is addressed. The complicated contour error pre-compensation problem is converted into a solution of simpler linear equation system using the least-squares technique, and an adaptive piecewise modulation strategy is developed for processing long toolpaths. Experimental and simulation results demonstrate the effectiveness and efficiency of the proposed method in improving contour precision.

Pre-compensation of contour errors for five-axis machine tools through constructing a model reference adaptive control

Qun-Bao Xiao et al.

Summary: This article proposes an adaptive contour error pre-compensation method for five-axis machine tools by constructing a model reference adaptive control for a feed drive system. The method transforms the control signals from the external PPI controller to match the response of the real plant with the nominal model. Through model matching, the tool tip and tool orientation contour errors can be precisely predicted regardless of modeling errors. The compensation signals are solved directly in the WCS using the MPC algorithm.

Linear programming feedrate optimization Adaptive path sampling and feedrate override

Petr Petracek et al.

Summary: This paper focuses on two aspects of feedrate optimization using linear programming methods: the effect of curve sampling on time optimization of the feedrate profile, and a method for adapting the feedrate profile in response to a feedrate override command. The results show that using a curvature adaptive sampling approach can significantly reduce machining time for tool path curves with high curvature variation. Additionally, the paper proposes a method for calculating a new feedrate profile in response to a feedrate override command, which ensures consistency with the currently active profile and minimizes the arc length required for transition to the newly commanded feedrate.
