How to improve the accuracy of CNC machining product

362 Published by admin Nov 14,2019

The methods for improving machining accuracy of CNC machining product can be summarized as follows: reducing original error, compensating original error, transferring original error, equalizing original error, homogenizing original error and machining in place.

1. Reduce the original error

This kind of CNC machining product is a kind of basic method which has been widely used in production.It is after finding out the main factors of CNC machining product error, trying to eliminate or reduce these factors.

2. Compensation for original error

Error compensation is the artificial creation of a new error to offset the original process system error.When the original error is negative, the artificial error is positive; otherwise, it is negative, and try to make them equal.

3. Transfer the original error

The error transfer method is essentially the geometric error, mechanical deformation and thermal deformation of the transfer process system.

There are many examples of error transfer method.Such as when the accuracy of the machine tool can not meet the requirements of parts processing, often not blindly improve the accuracy of the machine tool, but from the process or fixture to find a way to create conditions, so that the geometric error of the machine tool to do not affect the processing accuracy.

4. Divide the original error equally

In CNC machining product, machining errors in the machining process are often caused by blank or upper process errors (hereinafter referred to as the “original errors”).The essence of this method is the original error according to its size are divided into n groups, each group of blank error range is reduced to the original 1/n, and then according to each group adjust processing.

5. Homogenize the original error

Grinding process is often used for shaft and hole with high precision.The grinding tool itself does not require high precision, but it can be in the process of relative motion with the workpiece on the workpiece micro cutting, the high point is gradually ground off (of course, the mold is also part of the workpiece grinding), finally make the workpiece to achieve a high precision.

6. Local processing

In CNC machining some of the product and assembly accuracy problem, involving the relationship between the parts or components, and is quite complex, if blindly to improve the precision parts and components itself, sometimes not only difficult, even impossible, if the on-site processing method (also known as its processing and replacement method) method, could easily to solve the problem of the accuracy of the looks very difficult.
