“…Because the Spherical Two-Circle method (STC method) proposed by Lin and Lin [1] can easily transform CL data into NC data for a variety of 5-axis machining tools, this study utilizes STC method as the tool for coordinate transformation. Details as follows: B = ± cos -1 k.…”

“…This study explores this particular phenomenon, and proposes a programming method of calculating interpolation points and tool orientations that resolve this distortion problem. This method comprises the following steps: (1) Transforming CL data into NC data: transform the given CL data into NC data in order to insert necessary interpolation points between NC data. (2) Programming Tool Orientations: propose a tool orientation vector programming formula so as to program tool orientations of interpolation points.…”

When operating a 5-axis linear cutting command G01, the controller automatically inserts point data between two NC blocks in a linear distribution fashion, and then drives the cutter along these inserted points. If a simultaneous 5-axis machining is initiated, and CL data is directly transformed one-to-one into NC data, and then cutting is performed directly without having the 5-axis controller inserting any points between NC blocks, its processing path will deviate from the original plotted path. In fact, the processing path is no longer a straight line, but a curve line. This study proposes a method to increase CL interpolation points to automatically rectify the path deviation. The extent of research of this study comprises: (1) Transforming CL data into NC data (2) Programming tool orientations (3) Obtaining all CL interpolation points and their tool orientations (4) Generating NC data.
