When the outer spherical bearing parts processing pay attention to three things

When the outer spherical bearing parts processing notices three sources: bearing | last updated: - 2020 08 - 27 when the outer spherical bearing parts processing pay attention to the three items: 1, the feed back knife fixed mode each tool from the tool change points at G0 pattern movement to feed, feed two points should be in the X, Z direction a certain distance from the workpiece, far too close. Too far will increase the idle motion of G01 feed, processing efficiency is low; Too close to increase security hidden danger. When the feed ( Started from the cutting point to processing point) Have to feed in a G01 way, return have to retreat in a G01 way to recede cutter point ( Return point distance artifacts have a safe distance) After the movement in G0 manner. 2, develop a specification debugging action (1). We must beat G0 speed selector switch on the F0 block, make knives at a slower rate close to the workpiece, otherwise, if the cutter knife bias incorrectly, the cutting tool from the tool change point in G0 way very fast movement to the feed point, may be strong to collide and artifacts, disoriented, let operators to eliminate danger; Instead we make tool at a slower speed approached, even if the cutter deflection value is wrong, we also have plenty of time to adjust. (3) outside the spherical bearing in the process of debugging, the operator can put a finger in the circulation on the start button, another keep a finger on the loop button, so that in times of emergency can in time to stop the execution of the program. Also keep in mind the location of the emergency button, so that a rainy day. The above approach is to reduce by programming in numerical control car and improper operation and cause damage to the numerical control lathe, reduce the happening of the accident, to ensure the safety of the work, practice. (2) in the debug, must make the machine in the single-step state. After the operator on the machine to perform a statement, must check again under a cluster and rationality, and make adjustments accordingly. When the machine is moving, the operator must always observe the change of cutter coordinates on the screen and the procedure of coordinates and tool motion coordinates are consistent. 3, change the knife point set of modular tool change point is related to the processing efficiency and security issues. In cutting point set too far, cutting tool from the tool change point movement to feed some time will be longer, reduce the efficiency; If too close, when the tool change interference may occur and the workpiece, cutting tool, workpiece and machine tool damage. , therefore, has set itself in cutting point, that point could be set up or far or near, so I use subroutine according to the actual situation of the cutting tool and workpiece in knife fixed point, just put the tool back to back when in blade knife point, and then calling the subroutine, it greatly reduces the accidents.
