On a CNC 4-axis machining center with a rotating worktable, the coordinates of any point on the workpiece and the angle between the normal direction of the point and the Z axis of the machine tool are known. The macro program can quickly find the new point of any point of view of the workpiece rotation. Coordinates enable the tool to quickly and accurately locate the new point after the worktable is rotated, and then complete the coordinate tracking function of the arbitrary point. Programming in the normal plane of the point can easily complete the rotation of the coordinate system. When performing multi-face machining of messy workpieces, it can reduce the alignment intensity of workers, while simplifying programming, and the power is greatly improved, which has strong practical significance.
In the actual production of CNC 4-axis machining, the precise positioning advantages of this macro program are reflected in the following aspects:
CNC 4-axis machining
1. Simplify calculations and simplify programming
It avoids rotating the CAD Model in computer-aided design software to obtain the coordinates of each point, and also eliminates the need to use computer-aided manufacturing software to compile CAM tool paths. It only needs manual programming to reach the intention, saving investment and At any time, greatly improve the programming power.
2. Improve power and reduce intensity
Only need to align one datum at a time, and then contact the view point according to the size of the drawing, you can accurately locate the coordinates of the tool at other points, avoiding the selection of different datum aligning methods for different processing surfaces , Reduce the intensity of manual labor, and reduce the time of shutdown setting and debugging.
3. Expand the system and improve the level
CNC 4-axis machining uses a macro program to transform coordinate rotation, and after modifying the system parameters, it is set as a G code that can be used by the user. It is simple and convenient when programming the program, and it is clear when viewing the program. This enriches the user function code and improves the four-axis machine tool. Level of use.
