CNC machine tools in the process of machining the workpiece, sometimes appear on the surface of the workpiece tool lines, tool marks and other phenomena.
Not only to affect the surface finish of the workpiece more on the processing data caused by measurement errors.
How to effectively eliminate these two kinds of scenes needs to be analyzed from both the mechanical and electrical process points of view, step by step.
First of all, it is necessary to determine whether it is a regular vibration pattern. Then, investigate the cause of the vibration pattern once it appears.
Ultimately, the goal is to find an effective solution to eliminate the vibration pattern. This ensures that the machined workpieces achieve a higher degree of precision. It also helps avoid the creation of defective parts that could result in waste.
Tool pattern processing method
When the CNC machine tool processing workpiece surface tool pattern, there will be regular tool pattern and irregular tool pattern, as shown in Figure:.
Generally, check according to the following process steps.
Processing method of receiving tool marks
CNC machine tools in the process of machining the workpiece, will also appear on the surface of the workpiece, such as tool marks, which is divided into step marks, into the tool marks, corner marks, as shown in Figure.
Step marks: in plane machining, servo axis round-trip movement or unidirectional feeding will appear step phenomenon.
Entry mark: When the tool is cutting, it leaves a slight mark in the entry or exit position.
Corner marks: When machining the side, straight line into the corner, or corner out of a straight line there are slight cutter marks.
Generally check according to the following process steps.
Electrical parameters debugging processing methods
In addition to the mechanical point of view to study the CNC machine tool processing surface tool lines, tool marks and other phenomena, but also from the electrical point of view of such problems to be investigated.
Such as the use of FANUC system SVGUIDE software can effectively control the adjustment parameters, such as compensation torque, change acceleration and backlash acceleration and other parameters; improve the machine tool gain, thereby eliminating machining errors, improve machining surface finish.
Summary
Only mechanical and electrical aspects of the combination of methods to analyze the cause of the failure, in order to fundamentally solve similar related problems, and to improve the processing of machine tools operating conditions, to provide effective technical process support.
