What is the origin of the woodworking engraving machine?




What is the origin of the woodworking engraving machine? The origin of the engraving machine is a point determined at the beginning of the work. All the work engraving contents must use this point as a relative reference to work. This shows the importance of this origin setting, only the origin can be set to work smoothly. Then how do we set the origin when we use the wood engraving machine? Next, follow the CNC network Xiaobian to understand what the origin of the woodworking engraving machine is related to the origin of the engraving machine!
The origin of the workpiece is the origin of the workpiece coordinate, which is the origin determined for the workpiece size, and is generally the starting point of the workpiece machining. The origin of the workpiece can be selected by the programmer, and its relationship with the machine origin is determined by "setting the current point workpiece origin".
After we have determined the workpiece origin, no matter the position of the woodworking engraving machine running to the workbench, just select the "Return workpiece origin..." option under the operation menu, the tool tip automatically returns from the current position in the order of X, Y, Z. The origin of the workpiece.
In order to return to the origin of the workpiece, the tool tip can safely pass through the passing space without accidents due to obstacles such as workpieces and fixtures. Therefore, the zero return path is optimized as follows: if the end Z coordinate is greater than the starting Z direction For the coordinates, the Z axis is fed separately to the Z axis end position. Then, the X and Y axes are linked to reach the destination point. If the Z coordinate of the end point is smaller than the Z coordinate of the starting point, the X and Y axes are first linked to the destination point X. Y coordinate, then the z axis is fed separately to the z axis end point coordinates. Because the Z coordinate of the end point is often on the machined surface of the workpiece, in order to avoid hitting the workpiece surface or the tool tip after the tool tip returns to the workpiece zero point, in fact, the Z axis is not back to zero, but an offset value above the zero point. This value is set by the "retraction point" in the machining parameters of the "woodworking engraving machine system parameter window". Generally this value can be set to 10 mm.
CNC engraving machine mechanical origin:
The engraving machine is a mechanical unit controlled by a numerical control system. The system itself only knows the current position relative to the previous position. It is necessary to select a reference point so that any position on the machine has a fixed coordinate as a parameter. This reference point is the mechanical origin. .
How to set the mechanical origin of CNC engraving machine:
If you have a limit, you can return to the machine's origin, or you will bump into the machine. In the Weihong system, point the operation point back to the machine origin.
CNC engraving machine workpiece origin:
The workpiece origin refers to the origin of the workpiece coordinates and is the origin determined by programming the workpiece dimensions. The origin of the workpiece can be selected by the programmer, which is generally the starting point of the workpiece machining. When we select the “Return to workpiece origin...” option, the tool tip will automatically return to the workpiece origin from the current position, and the tool tip will actively return to the workpiece origin from the current position.
CNC engraving machine specific zero return method:
1. If the end Z direction coordinate is greater than the starting Z direction coordinate, the Z axis is fed independently to the Z axis end orientation, and then the X and Y axes are linked to reach the intended point.
2. If the coordinates of the end Z direction are smaller than the coordinates of the starting Z direction, the X and Y axes are first linked to the X and Y coordinates of the intention point, and then the z axis is independently fed to the z axis end coordinate.
Since the Z coordinate at the end is often in the machining appearance of the workpiece, in order to prevent the tool tip from returning to the workpiece zero point and then hurting the workpiece surface or the tool tip, in fact, the Z axis is not returned to zero, but an offset value above the zero point. This value is set by the "Retraction point" in the machining parameters of the "System Parameter Window".
