How to analyze the offset of the origin of the CNC machine program The professional CNC machining manufacturer teaches you how to analyze the offset of the origin of the CNC machine program. In the programming process, in order to avoid the size conversion, the workpiece coordinate system can be translated. The workpiece coordinate system (programming coordinate system) origin is translated to the workpiece reference, called the offset of the program origin. Cnc CNC machining Generally, six CNC (C54 - C59) workpiece coordinate systems can be set. The values ​​of the coordinate origin of these coordinate systems in the machine coordinate system can be input by manual data input, stored in the CNC machine memory, and still exist when the CNC machine is restarted.
Once one of C54~C59 is specified, the origin of the workpiece coordinate system is the current program origin, and the absolute coordinates of the workpiece in the subsequent block are relative to the origin of the program. For example, the following program: Welcome to the company **http: //
N01 C54 COO C90 X30 Y40, N02 C59N03 COO X30 Y30, when executing N01 sentence, the system will select the G54 coordinate system as the current workpiece coordinate system, and then execute the coo to move to the ^ point in the coordinate. When executing the N02 sentence, the system will select the C59 coordinate system as the current workpiece coordinate system. When the N03 sentence is executed, the tool will move to point B in the C59 coordinate system just specified, as shown in Figure 2-18. The C92 command requires a coordinate value to specify the current workpiece coordinate value. Therefore, a separate block designation is required. Although there is a position command value in this block, it does not produce a cow movement. In addition, before using the G92 command, the CNC machine must be guaranteed to be at the machining start point, which is called the tool setting point.
When the workpiece coordinate system is established using G54~C59, the command can be specified separately or in the same segment as other programs. It should be noted that when the C54~G59 is used to create the coordinate system, if there is a position command in the program, motion will be generated. Before using this command, you should first input the coordinate origin of the coordinate system by MDI, and then use the corresponding C54~C59 in the program to establish the zero coordinate system, and use the CNC machine positioning command to move the white position to the T position. Start point.
