Now we will discuss about the description of the NN itself. Let's look at the picture "Schematic lay-out of NN device"
Schematic lay-out of NN device
NN device consist of:
- A module for recognizing of geometric and technological features from CAD model of the part,
- Computer CAD model of the part, which contains geometric and technological features,
- NN device for milling, which has been learned for NC programming of milling, drilling and machining operations like drilling and
- NC control program for the part, which has been sent to control device, as a CAD model of the part.
In the phase of learning the NN device is connected to the module for learning of the neural network, which takes the data from the usual, commercial available CAD/CAM system, which is used for programming of NC/CNC machine tools. NN device automatically generates NC programs for CAD models of each individual product, which it becomes from the commercial CAD/CAM programming system. CNC control unit after this invention can receive the data for teaching of NN device from a special module for teaching, which is not the constituent part of the control unit. The task of the module for teaching is to teach the neural network, which is built-in into NN device, the principles and the technology of NC programming of all machining operations on CNC machining centres, mostly milling, drilling and operations alike.
In principle for this purpose different systems of neural network and different, also commercial developed software, can be used [9,10,11]. If we want to meet special criteria at machining (costs, time, quality of cutting, tool life, high speed cutting etc.) special developed neural network must be used.
