Introduction in recent decades, research on the development of CNC machine tools and industrial robots has entered a mature stage.
Manufacturing Automation by implementing industrial robots and modern CNC machine tools with high-speed and high-precision machining facilities, greatly improves the productivity and flexibility of the manufacturing process.
In addition to this, the normalization provided by G code leads to faster and easier application configuration settings and implementation.
With these aspects in mind, more and more research in this area is focused on new application development (
Especially in the field of virtual prototype and functional simulation of modular flexible manufacturing system)
Digital manufacturing and process control optimization implemented through new information technology (Enciu et al.
, 2009 and Nicholas library and others. ,2009). 2.
Flexible manufacturing unit virtual prototype flexible manufacturing unit (see Fig. 1)
The virtual prototype environment of Catia V5 was developed.
The manufacturing unit includes the following elements: * modular 4-axis gantry robot for part operation (see Fig. 1)
, Three ISEL standardized modules with X, Y, Z linear positioning axes, fipro standardized module of C axis of rotation and doctor pneumatic standardized Gripper (
* Years, * years);
* Modular 3-axis CNC Machine Tool for part manufacturing, three ISEL standardized modules with X, Y, Z linear positioning axis, standardized electrical direct linkage tool-
Head drive systems and standards (modular)
Partially fixed vacuum system;
* Complementary structural elements for Modular CNC machine tools configured using ISEL standardized mechanical elements for supporting beams, columns, angle reinforcement brackets, connecting plates, covers, etc.
* Four standardized linear delivery modules for the income/results of two different parts families in a flexible manufacturing unit, as shown in the figure1 (***, 2009a). [
Figure 1 slightly]3.
After the components of all flexible manufacturing units are mutually constrained and the workspace/component distribution is verified using specific functions, the manufacturing unit programming and simulation are performed using MACHSIMSOFTWARE, modular CNC machine tools export gantry robots and conveyors using the \"mechanical menu (
STL quick prototype option)
Software interface.
Convert all solids to simple surfaces using the mosaic option.
Therefore, each component is saved as an aSTL file separately. The zero (origin)
Point of machine tool coordination system OM ([0. sub. M], [0. sub. M], [0. sub. M])
Has been defined at the geometric center of the x-axis machine tool table, supporting the manufacture of parts.
Characteristic end of machine tool-point[O. sub. T]([0. sub. T],[0. sub. T],[0. sub. T])
Has been set as the feature contact point of the tool in machining.
By defining the compass operation parameters, these settings are also done in the solidworks environment.
Special software \"MachSIM\" was used in order to manufacture unit programming and functional simulation \"(Fig. 2).
In order to develop the above application in MachSIM (***,2009b)
First, create a new project by accessing the \"NewMachine\" option.
The flexible manufacturing unit is then configured and further Machine/Gantry robot programming and its functional simulation are performed in accordance with the following detailed procedures:
