Brief Introduction to Workpiece Coordinates of Longmen CNC Milling Machine

There are two ways to specify the polar origin: one is to use the zero point of the workpiece coordinate system as the polar origin; Another approach is to use the current position of the tool as the origin of the polar coordinate system.

When using the zero point of the workpiece sitting system as the origin of the polar coordinate system, specify it using absolute value programming. For example, in the machining center program "G90 G17 G16;", the polar coordinate radius value of the gantry CNC milling machine refers to the distance from the endpoint coordinate to the programming origin; The angle value refers to the angle between the line connecting the endpoint coordinates and the programming origin and the X-axis.

When using the current position of the tool as the origin of the polar coordinate system, specify it using incremental value programming. As in the program "G91 G17G16;", the coordinate radius value refers to the distance from the endpoint to the current position of the tool; The angle value refers to the angle between the line connecting the origin of the previous coordinate and the origin of the current polar coordinate system and the current trajectory. If C91 polar coordinate programming is performed at 4 points, point A is the origin of the current polar coordinate system, and the origin of the coordinate system before the machining center is the programming origin (point O), then the radius of the CNC machine tool is the distance from the current programming origin to the trajectory endpoint; The angle is the angle between the line connecting the origin of the previous coordinate and the origin of the current polar coordinate system and the current trajectory. When programming the BC segment, the month point is the origin of the current polar coordinate system, and the determination of angles and radii is similar to that of segment AB.

What are the requirements for the installation of gantry CNC milling machines? When installing and using gantry CNC milling machines, in order to ensure the quality of installation, the following requirements need to be met. Let's learn about it together now.

Before installation, it is necessary to check the bearing capacity of the ground surface.

2. The required machine tool must meet the relevant requirements in terms of rigidity, strength, and stability.

3. Strictly abide by the relevant national construction design standards and regulations.

4. The purchase requirements must include technical maintenance and support, as well as design proposals and various indicator drawings.

5. Accurately arrange the size of the milling machine and its relationship with the factory interview, and equip all relevant auxiliary facilities.

6. Necessary lighting and energy supply pipelines need to be considered.

7. The working environment of the milling machine needs to meet the standards.

8. Ensure precise installation of the body and improve installation quality.
