Minimization of the kinematics error for five-axis machining

Kinematics of a particular five-axis milling machine can drastically change the machining accuracy. Therefore, the reduction of the kinematics error is an important problem associated with the tool path planning. Our newoptimizationmethod employs a closed formof the kinematics error represented as a function of the positions of the cutter contact points. The closed form is derived from the inve...

Tool Path Modification Approaches to Enhance Machining Geometric Accuracy in 3-Axis and 5-Axis Machining

-axis CNC machining of sculptured parts

As an innovative and cost-effective method for carrying out multiple-axis CNC machining, 3 1 2 1 2 -axis CNC machining technique adds an automatic indexing/rotary table with two additional discrete rotations to a regular 3-axis CNC machine, to improve its ability and efficiency for machining complex sculptured parts. In this work, a new tool path generation method to automatically subdivide a c...

Toward 5-axis High Speed Machining

We present a scheme to construct C1 continuous toolpath for 5-axis pocketing of high speed machining. A continuous toolpath synthesis is proposed, that forms out circular segments of maximally inscribed sizes and linear segments connecting these circular segments. Extending earlier work that employed the Medial Axis Transform to compute these maximally inscribed circles for 2D planar pockets, t...

Advanced Control Technologies for 5-Axis Machining

Demand for 5-axis machine tools has grown rapidly with the appearance of high-performance machines and growing requirements for high-efficiency to enhance competitiveness. To meet market needs, FANUC provides innovative CNCs, including the FS30i-A and FS31i-A5, that control up to 24 axes simultaneously with maximum paths of 10 enabling high-speed and high-precision multiple-axis and path contro...
