Here we discussed on the best surface finishing of the die mould machines. The technology of “SSS” (Super Smooth Surface) control provides an optimal speed control function for machining die mould with smooth surface.Conventional problemAs for the mould machining of three-dimensional shape, the smoothness of the machined surface (surface accuracy) is important. In recent years, even at the case of more than 5m/min feed speeds, the request of high surface accuracy in several μm or less has increased especially. In this case, the quality of instruction shape described in the machining program is often regarded as a problem.
Generally, in CAM to create a machining program, the motion curve of the tool relative to the workpiece is calculated by approximating the minute line segments. Therefore small error is more or less included in the data of minute line segment. For example, as shown in Fig.1, there are many cases like the minute error of the zig-zag shape or the shape of a level difference is contained within the limits of the permissible error (tolerance) on CAM processing, to form the process originally.
In NC, it’s essential to have the process of determining the rate at which moves according to the shape in order to maintain the trajectory accuracy. If some errors are included in the instruction shape, it is difficult to calculate the accurate determination of the appropriate speed movement. Especially in scan line machining, there are some cases that the fluctuation occurred in the trajectory of movement of the machine and scratch streaky occurred in the machined surface when the magnitude of the error contained in the instruction form by path difference.
