In addition to the reasons of Nordson Automatic CNC Machine itself, the processing accuracy and efficiency of the workpiece should be comprehensively considered from several aspects such as reasonable setting of processing routes, selection and correct installation of cutting tools, and reasonable use of tools. Selection of cutting amount, programming skills and quick control of dimensional accuracy.

Automatic CNC Machine is the basic work of CNC machining. The quality of workpiece machining program directly affects machining accuracy and machine efficiency. We can skillfully use the inherent program, reduce the cumulative error of the numerical control system, and flexibly use the main program and subroutine.

1, flexible use of the main program and subroutine

In the complex mold processing, the mold form is generally used for multiple processing. If there are multiple parts of the same shape on the mold, the relationship between the main program and the subroutine should be flexibly used, and the subroutine should be repeatedly called in the main program until the processing is completed. It can not only ensure the consistency of the processing size, but also improve the processing efficiency.

2, reduce the cumulative error of the numerical control system

Generally, the incremental way to program the workpiece is used as a processing benchmark, so many continuous program cycles will produce a certain cumulative error, so as far as possible in the programming way to program, so that each segment is based on the origin of the workpiece, so that you can reduce the cumulative error of the CNC system to ensure processing accuracy.

Processing accuracy is mainly used to produce the degree of product. Machining accuracy and machining error are terms used to evaluate the geometric parameters of a machined surface. However, the actual parameters obtained by any processing method will not be more accurate. From the function of the part, as long as the machining error is within the tolerance range required by the part drawing, the machining accuracy can be guaranteed.

Machining accuracy refers to the degree to which the actual geometric parameters (size, shape and position) of the machined part conform to the ideal geometric parameters. The difference between them is called machining error. The size of machining error reflects the machining precision. The greater the error, the lower the machining accuracy, the smaller the error, the higher the machining accuracy.
