CNC drilling machine is a widely used equipment for sheet metal processing. This article will introduce in detail the CAD programming operation method of CNC drilling machine for readers to learn and refer to.
1. The format of the first two lines of each workpiece program is fixed, as follows:
2. For flange parts:
3. The thickness of the workpiece is 20, such as 20mm.
4. C: 1000 – indicates the diameter of the workpiece, such as 1000 mm.
5. The diameter of the drill bit is 20, for example, 20 mm.
6. The second line describes the overall dimensions of the workpiece, including diameter, thickness, and hole diameter. The fourth line begins with the main body of the program. The statement format is set according to the programming instructions, and the actual program statement can be directly generated through the shortcut function of the editing interface.
7. For flat parts:
8. The thickness of the workpiece is 20, such as 10mm.
9. Workpiece length L: 1000, e.g. 1000mm.
10. The width of the workpiece is 500, such as 500 mm.
11. The diameter of the drill bit is 20, for example, 20 mm.
12. The first four lines indicate the overall dimensions of the workpiece, including length, width, thickness and drilling diameter. The fifth line is the specific content of the program, and the format is determined according to the programming instructions. The actual program statement can be generated directly with the help of the shortcut function of the editing interface.
13. Precautions:
14. The system has the function of user coordinate system, which can establish a temporary coordinate system according to the actual graph to facilitate coordinate calculation. It should be noted that the G90 and G91 instructions under this programming method have different meanings from G90 and G91 in the FAGOR 8055M CNC programming manual, so please distinguish them when using them.
15. The syntax format of G91 is G91 Xxx Yxx @xx, for example, G91 X50 Y50 @30表示创建一个新坐标系, its origin is located at (50, 50) position in the original coordinate system, and the X axis of the new coordinate system is at an angle of 30° (angle range 0≤ @ ≤ 180°). With G91 enabled, the body text still uses the format of Xxx Yxx Jxx Lxx Nxx, but all values are based on the new coordinate system. If you need to switch back to the original coordinate system, you must add a line of G90 instructions in advance.
16. CAD programming:
17. Many manufacturers use AutoCAD and other software for computer-aided design, and this system has developed interface programs with CAD software. Through this interface, the partwork program designed in CAD can be easily converted into the format required by the system, realizing a seamless connection from design to manufacturing, and truly completing the process of computer-aided manufacturing (CAM).
18. The operator selects the flange or plate type according to the type of workpiece, and switches the corresponding function program for conversion operation.
19. When performing CAD programming, you need to pay attention to the following points:
20. CAD drawing files need to be converted to DXF format, and all kinds of CAD software can achieve this function.
21. CAD drawings must be strictly based on the actual size, otherwise the generated data will be inaccurate.
22. The system automatically adopts the CAD coordinate system and sets the minimum X and Y points of the drawing as the conversion base point, that is, the zero point.
23. When drilling, use the same type of drill bit first, and proceed in the order of the same Y value and X value from small to large.
24. If an unexpected error occurs, please check whether the drawing is standardized, and focus on confirming whether the hole diameter is consistent with the drawing requirements.
