ANALYTICAL MATHEMATICAL SIMULATION OF RK-WIMBLING WITH SQUARE SECTION
The Reuleaux triangle is able to rotate within a stationary square frame maintaining four-point contact between them. We have worked out laws of motion of the vertex and the centre of the Reuleaux triangle in the coordinate system of the square frame. By differentiating we have worked out laws of velocities and acceleration. Worked out laws let us simulate the process of wimbling with square cross section, they let us estimate uneven cutting, geometric and dynamic processing errors, they can be used in control programme development for machines with CNC.
