Processing center lathe machine tool change tool fault treatment
One: failure phenomenon
In the use of CNC machining center production of Daewoo, FANUC operating system, workers in the process of the product, because the product clamping errors, caused the crash, the origin of machine down, can not change the normal mechanical hand knife.
Two: treatment method
1. first use the M39 order, make the machine tool in the maintenance state, let the machine tool after the machine handle switch into manual mode, let the manipulator back to the original state.
2. if the machine can not go back to the original operation, modify the K12 parameter.
3. back to the origin after observation, not the origin of machine tool change position in manipulator we know that the spindle is too low, the manipulator will change the knife in the knife because of the change in position is too low and damaged machine, finish the ATC Work; too high, manipulator can complete the tool change, but the mechanical hand to the spindle. Because did not reach the position of cutting tool is not tight, resulting in falling knife phenomenon.
4. we know that Daewoo CNC machining center tool change command execution, execution will start at zero, and zero program in the G28Z0 directive, that is to say, whether the Z axis stopped at any position, if the program is ATC instructions, go back to the origin of machine spindle, and then execute the tool change command, NC with the processing center of Taichung machinery production, once the implementation of ATC instructions will be executed as G30Z0, go back to the second machine mechanical origin, and then change the knife instruction, thus completing the ATC work. If the damaged position inadvertently CNC machining center spindle Taichung machinery production knife can be Z axis by adjusting the parameters of the 1241 positioning, positioning, through 4031 parameters can be adjusted spindle positioning angle so that we try to 1240 parameter adjustment, did not achieve the desired purpose.
5. we would like to adjust the mechanical origin of the limit block, the origin of machine to move upward or downward, so that the machine stops at the best mechanical hand tool change position, but did not succeed, no matter how we adjust the origin of machine, machine tool in a certain range is changing, not to change the knife position, finally, we use the the adjustment method of servo motor encoder, the encoder to rotate an angle, through this method, we got the best in spindle positioning manipulator tool change position, angle of rotation servo encoder can control the display adjustment.
