1. Research on simulation state of three- axis machine tool processing program
First open the VERICUT6.1 application software , create a new project type, and add the original FANUC three-coordinate control system and machine tool module in the setup-CNC machine . Select the component tree under the configuration menu. Figure 1 shows all the components of a common three- axis machine .
figure 1
The simulation of ordinary three-axis parts is based on the existing control system and machine tool module provided by the manufacturer, adding blanks, coordinates, tools and programs to complete the simulation processing of the three- axis machine tool . The machine tool module is limited to the ordinary three-coordinate machine tool simulation processing three-axis product parts, and can not meet the program simulation of multi-axis machining technology.
2. Increase machine components
In order to achieve multi-axis machining simulation, we need to add the fourth axis A axis to the original three-axis machine module, but we must understand the motion relationship between the various parts of the machine before adding the module. Through the study of the ordinary three-coordinate machine tool , we can understand the motion relationship between the major components. We can know that the fourth axis A axis to be added should be attached to the X-axis. Add the A rotation characteristic under the X axis through the component tree, as shown in Figure 2.
figure 2
Adding machine parts to the A rotation attribute, we add a part body rotating around the X axis on the ordinary three-axis machine tool , and by selecting functions such as moving and rotating in the software , the newly added parts are placed in the same position as the real machine tool , thereby realizing the simulation machine tool. The purpose of the part is the same as the real machine .
Note: The added machine part position must match the A rotation attribute position.
3. Verify A-axis simulation processing
After successfully adding the machine A-axis assembly, we tested the machine parts that have been added.
A simple CNC running program is shown in Figure 3.

Start the simulation after establishing the corresponding system, tool , program, coordinates, and parts of the machine configuration. The results of testing the newly added machine components prove that the VERICUT simulation software can now simulate the A-axis of the four-axis machine (see Figure 4).
Figure 4
By exploring the application of VERICUT simulation software , the A-axis program simulation of the four-axis machine tool is realized, which largely eliminates the damage of parts or machine tools caused by program errors, reduces the on-site debugging time of the program, and greatly improves the production efficiency. It also accumulated valuable experience for simulation of other multi-axis CNC machining centers.
