10、purpose aggregate machine-tools has had the milling and cutting power “the versatile machine”. according to the material introduced that the most remarkable characteristic is in these engine bed whole has the intuition. the anti-collision preservation technology was already mature, in certain circum

11、stances, even if uses the manual operation pattern, can also avoid the occurrence which collides. because the control software has the very good intuition, the user operation friendly degree unceasingly is also enhancing. believe the multi-purpose aggregate machine-tools by its survivability world-w

12、ide in the more different processing scenes. the off-line programming optimization and the nc automatic control systems formation already made this technology to be easier to accept, when therefore uses the procedure when the engine bed, does not need to spend many time tune-up procedure and confirm

13、ed that some part does not have the question. if components need to provide the high and low two revolving tool box saddle simultaneously to carry on the rough machining, in this kind of situation the programming is quite difficult, because it needs two revolving tool box saddles also to feed. the a

16、ide the 3d pattern now “the hypothesized engine bed”, has custom-made according to some specific models engine bed. the result indicated that the simulation processes not only the fabricated parts and the actual end product is similar, is the one-to-one copy simply. the intuition type control interf

17、ace, the simulation as well as other software technique are progressive, the more production workshops have opened wide the front door to the multi-purpose aggregate machine-tools, but if does not have the corresponding knowledge to train and to solve the question creativity, the manufacturer is als

18、o very difficult to realize and the full use advanced engine bed flexibility aspect superiority. the work which does to the machine are more, the machine will be more complex, also needs to have the stronger skill person correspondingly to be able to operate it. if machinist past one day operated 3

19、engine beds, then he has this kind of multi-purpose engine bed now, might produce more components. more importantly, he may draw support from softwares help to cause the production efficiency to be higher, regarding transformation processing components preparation, may also establish the processing

20、craft plan. because the replacement components need to lower 3 main axles, therefore before replacing the components, the workshop should process as far as possible many components. regarding the multi-purpose engine beds, the transformation components speed is quick, the production batch of time in

21、terval is shorter, the stock is lower, the production efficiency is higher. can use multi-purpose engine beds some workshops fully, very quick will discover the post function the unification. now, a workshop may only use an operator, an adjuster and a programming teacher, in the future these 3 work

22、definitely may do by a person. in the traditional post description the machinist will transit becomes one to adjust engineer, if this engineer the familiar components processing programming, that were also more ideal. regarding such transformation, training has been simple, so long as trains 1 indiv

23、idual line, but is not 3 individuals. looking from the long views, this will provide to the people the higher post degree of satisfaction. when adjusts engineer to be responsible to process the programming, and pays attention to the components processing personally time the entire process, he comple

24、tely has become this components control. in addition, but should also makes more effort in the cutting tool choice and the programming aspect, must make any model the multi-purpose aggregate machine-tool to succeed, the workshop needs to provide the skilled machinist, has ability and completes many

25、kinds of operations nimbly. therefore, crosswise training was at any time in the past more important. regarded as the milling and the lathe work the different discipline the viewpoint never to return. regarding the programmers, this belongs to their time. regarding personnel who will program, will u

26、nderstand the engine bed and controls it, this will be their ability manifestation. the cutting tool will choose most people not to install the passenger vehicle tire to the race car on, but processed the cutting tool to have such situation. the cutting tool should match with the new engine bed, is

27、conceivably redundant on the new engine bed uses the old cutting tool to the production efficiency influence. in order to match the multi-purpose aggregate machine-tools, the new cutting tool and the cutting tool adapter technology was already developed. at present the industrial field is developing

28、 the development the processing cutting tool, may complete the turning on the identical tool rest, boring and drills truncates the processing, is only processes the phase to differ from regarding the work piece angle. the processing operates the difference even confuses is unclear. the new processin
