What causes precision parts machining to be prone to crashing
Author：
For the machining plant, the most worrying problem in the process of precision parts machining is that the machining center will collide with the machine. If a machine shop experiences a crash, machining efficiency will definitely be affected, and the machined workpiece should be scrapped, possibly resulting in personal injury. Therefore, it is necessary to clarify the reasons for the collision.
1, the most common cause of collision, is the tooling input error.
We know that the machining plant precision parts processing can not be separated from the tool. In CNC machining center, how the tool operates on the workpiece cutting, is required to control through the program. If there are input errors in the computer programming, it is easy to crash the machine. These input errors have many aspects, such as the workpiece coordinates G54 input errors, coordinate offset 60 input errors, radius G41 compensation D input errors or call errors, length G43 compensation H input errors or call errors, etc..
2, there is another category of crash causes, is the error manipulation.
If in the precision parts processing, attention is not concentrated, it is easy to open the wrong program, get the wrong processing coordinates, open the machine did not return to the origin, installed the wrong knife, hand wheel or manual target error, etc., will directly lead to the collision occurred.
3, unique processing procedures, will also lead to the occurrence of a collision.
For example, in the processing of the need to change the knife once, there may be a make-up error and crash; precision parts machining program at the beginning of the slant line down the knife, may also lead to a crash; in the mechanical reference point down the knife, and then back to the processing down the knife point, can also lead to punch the platen or screw.
