The calculation of the curvature of a complicated free-form surface for optimizing five-axis machining
Original language description
The article deals with the five-axis machining of a complicated free-form surface. There are many problems associated with the complicated shape of a surface when creating the NC tool paths. The first problem is with the control of the cutting tool (tiltangle and lead angle) for the whole free-form surface. The second problem concerns potential collision situations that arise from an inappropriate tilt angle of the tool (tool control). We present a method that allows the general area to be split into specific types of patches. This splitting allows each patch to use a different method of tool control and to use also a different diameter or type of tool. The division algorithm is created in the Matlab program. This algorithm uses the calculations of the curvature of a surface (Gauss, mean, main curvature). The article describes how to import any surface from CAD software into Matlab and to export data to a CAD/CAM system. STL is used as the input data format. Our own bespoke calculatio
