CNC lathe prevent crashes (collision) Notes 1 Press before the program starts, make sure the cursor if parked in the program to start. 2 program decimal point, sign and G00, G01, pay special attention to the position. 3 tool change position is necessary to make up the outside of the tool in the workpiece. 4. G50 instruction within a single section to avoid the X, Z, T, etc. appear. 5 automatic cycle, the starting point of the turning loop instruction covering the outer diameter of the workpiece to be on the outside, When the turning 俓 need in the hole, if the ATC instruction execution G70, To be at the same starting point. 6 Each time after the completion of G41 or G42, G40 must be performed to avoid Correcting the cumulative result of a collision. After 7 preview and change program must re-test. 8. path display function in school knife after the first mechanical lock to run the program, Check that the path is correct. After 9 mechanical lock to be re-homing (If you run the program at the origin, Remove the need to re-OPR). 10. really perform test four steps. Note 11. test whether the program will be hit twice near the chuck (Especially the need to pay particular attention to the use of high long soft jaws). 12 Turning the hole when the test program, in order to prevent the tool crashes, soft jaws best out Zhang state. The first real test of a workpiece 13, rapid feed rate must be in F0 Or when (G00 low segment stalls), a day after the first boot turning workpiece, Rapid feed rate also in F0 or (G00 low segment stalls). Need special attention when the direction of movement of the workpiece 14, to chuck direction is positive, negative direction toward the tailstock. Do not press the MX 15. wear correction or MZ input (Fanuc system). 16. demand before the workpiece clamping length, a cutting end face do not exceed 4 mm, Workpiece easy flying should be avoided. The lock hole 17 in the tool holder blade, extending rearward in amounts not exceeding 20mm, When ATC tool to avoid interference with the base, screw on the sleeve should also make sure to fasten (Locking torque required to correct excessive force will cause damage to the screw or knife tool Tool tool to avoid shrinkage after turning. 18. chuck pressure to be appropriate, the clamping force is not enough to avoid artifacts caused by flying. (Can not be too general workpiece clamping pressure deformed). 19. G10 instruction execution halfway off, reboot required after the workpiece out of reset, Cheng shows performed from the beginning. 20. turning in different sound to immediately pressed the emergency stop switch, check the tool, workpiece, Whether a program or mechanical anomalies? 21. boot clad origin need not be normalized to avoid the OPR that the implementation of the program caused the crash. 22. mobile travel tailstock position whether it is appropriate to note, in order to avoid a collision. 23. really need to place workpiece clamping position rotation must first visually whether yaw. 24. others to be added ......
