Because numerical control lathe undertakes be machininged automatically by statement of program of institute of process designing personnel, although a lot of imitate emulates software now,can detect program, but as a result of,still meet all sorts of reasons, cause accident of collision of machine tool happening to happen from time to tome. The article arranged a machine tool technically to produce safety to operate a standard, remind the member that broad machine tool works the attention is safe. Install and debug level technology to ask environmental temperature and humidity ask. Numerical control lathe asks to use environmental constant temperature commonly, in order to ensure the working precision of the machine tool, ask 20 Celsius control constant temperature commonly. Many practice proves, period of summertime high temperature, the fault rate of numerical control system increases greatly, cause the happening of collision accident very easily. Damp environment also can reduce the reliability that numerical control lathe runs, because this answers to be adopted to environment of numerical control lathe,go wet measure, in order to avoid circuit short circuit, cause numerical control system to be operated by accident, produce collision accident. In the meantime, still ask numerical control lathe is far from the oscillatory source such as v equipment, be far from electromagnetism field to disturb, be far from electric welder, be far from the report such as line cut machine tool and electric spark machine tool to machine a machine tool. Raise those who become a standard to debug a movement, basically include the following: 1) when debugging a program, must make G00 speed select switch in F0 block, let cutting tool approach work with slower rate, otherwise, once the knife slants wrong, when cutting tool is nodded to feed with G00 kind moves lickety-split from the dot that change a knife, may produce intense collision with workpiece, let handlers not know what to do, have not enough time to remove danger condition; Contrary, when letting cutting tool be stood by with slower rate, although the knife slants,have by accident, handlers also has abundant time to give adjust. 2) when debugging a program, must make numerical control lathe is in the condition that weak condition carries out. Handlers carries out on one block in numerical control lathe hind, must check the correct errors sex of below one block and rationality again, make accordingly adjust. 3) numerical control lathe is in athletic process, the coordinate that the athletic terminus coordinate that handlers always must observe the change of coordinate of the cutting tool on screen and program are medium and cutting tool move actually is consistent. 4) the program debugs a process in, handlers can put a finger on the circular pushbutton that start, another finger is put in the loop to hold pushbutton edge, so that be in,urgent hour can stop the execution of the program in time. In the meantime, always remember the position of urgent pushbutton, so that untimely needs. When the machine tool that start, want to undertake machine tool reference point is installed commonly. Coordinate of machine tool workpiece is to answer to keep consistent with department of process designing coordinate, if make mistake, lathe tool and the possibility that workpiece collides are very large. In addition, compensatory of cutting tool length is installed must correct, otherwise, or is empty treatment, or is to produce collision. 5) of the program debug level to use computer simulation to emulate a function. As the development of computer technology, expand of CNC Machining education ceaselessly, emulation system of CNC Machining imitate is increasing, its function is perfect with each passing day. Because this can be used at preliminary check-out program, watch the sport of cutting tool, will produce collision whether likely certainly. Use numerical control lathe to machine a function from the graphical imitate of the belt. General relatively advanced numerical control lathe has graphical imitate to machine a function oneself, before be machined automatically, to avoid program mistake, workpiece of cutting tool collision or chuck, can undertake graphical imitate to whole treatment process, contrail of examination cutting tool is correct. The operating trouble that abides by operating rules strictly to drop numerical control device should want not only from from management, craft, groom, the much link such as supervisory examination undertakes precautionary, the basis pursues the research of the experience of numerical control and numerous case for years, we sum up a machine tool of the following numerical control to prevent operating trouble regulations, can have positive direct effect to the precaution of operating trouble: 1) numerical control equipment decides a person to decide machine operation, facility must not be not operated before qualified. 2) personnel must have done two above to talk things over when operation equipment hand over workpiece, forbidden change without operating personnel to agree with do sth without authorization facility status. 3) operation personnel should strengthen vocational study ceaselessly, raise responsibility heart ceaselessly. 4) before first treatment must microscope program, and classics is odd paragraph of treatment test is rear can undertake be machininged automatically. 5) after be being revised to program and data must close check, machine measure to carry out by first. 6) to process designing medium coordinate origin and the choice of the dot that change a knife must accomplish safety first, no risk at all. 7) reasonable choose cutting parameter, wait like quantity of rotate speed, cutting, feed, put an end to excess load to use device. 8) semifinished product of close check work, too big to semifinished product appearance (or too small) person must foreclose. 9) outfit of workpiece, prop places indispensible means, position reasonable, clamping force adjustment is appropriate. 10) clip of knife handle outfit is indispensible and firm reliable. 11) necessary discretion is attentive in the operation, collision happens when taking strict precautions against a hand to use mobile machine tool. 12) equipment appears unusual or accident hitting a car, must inform maintenance technician inspects equipment condition instantly, must not conceal protracted. 13) groom without major and approbate, forbidden adjust and revise machine tool parameter. 14) identify clear fact to explain according to the operation daily on time service facilities, fill in according to the facts watch of equipment spot check.
