Solution processing tool path generation and calculation

The main wing of the NC machining method, the key to solve the processing tool path generation and calculation, using a cubic B-spline curve fitting wing line, generating wing, find machining tool path to solve the cutting step, take the knife spacing, interference checking and correction and other issues. Through this thesis, main  abrasive grinding  are as follows: 1. Segmented design method based on feature point coordinates are calculated using the cubic B-spline curve fitting synthetic benchmarks wing  polycrystalline diamond , by fitting the wing airfoil surface equation constructed . This method greatly reduces the amount of calculation, to ensure smooth surfaces, reducing the surface intersection of computing and programming  synthetic diamond  brings inconvenience. 2 CL path section method used to generate tool paths. In determining the cut-plane direction, based on the method of using discrete discrete maternal side, according to the tool radius offset surface generation, solving the cross-sectional plane and the line of intersection of the surface is equidistant cutter location point trajectory.
