附录 Combines the cutting tool the reasonable use and chooses In order to adapt the product daily diversification which the manufacture technology faces, the higher production efficiency and the environmental protection request, appeared the high-speed cutting, the doing -like cutting one after another and so on the new processing technology. The high-speed cutting technology causes in the processing process the cutting time remarkably to reduce, this has used the effect which the new cutting tool material and the coating obtained. In this foundation, through further enhances the cutting parameter to enhance the productivity the potential to be extremely limited. Enhances the productivity another means reduces the non-cutting times far as possible. First, decomposed the complex components into very many working procedures and uses very many cutting tools the processing technique to occupy have very traded around the knife time and the working procedure transmission time. Reduces this time to enhance the productivity to have the practical significance. Was ntsconfirmed the very effective procedure is with the multi-purpose combination cutting tool substitution function sole standard cutting tool, but correctly chooses the effect which and the reasonable use combination cutting tool only then can obtain should have. 1 Combines the cutting tool the form Until now, combines the cutting tool to have the many kinds of forms. The common steps and ladders drill are one kind of simple combination cutting tool, its characteristic is center completes several knives identical kind of crafts in the processing. The more complex combination cutting tool frequently integrates may complete the different craft several knives, like can drill a hole can ills the milling cutter and so on to combine the cutting tool, usually must divide several time or completes several knives intern in the different location the cuttings. This is one kind of most typical combination cutting tool, may cover the very big processing scope, also has the simple drill hole - bevel edge combination knife, also has integrates 5 10 the knife special-purpose combination cutting tool. Also some one kind of more complex combination cutting tool: The ntsinternal integration has produces the assistance cutting motion transmission system or the rotation axis, has the mechanical type and the machinery two kinds, may satisfy the processing components special spot the request, such cutting tool often has the special request to the engine bed structure or the engine bed control system, realizes to the cutting tool movement partial controls. 2 Combines the cutting tool the merit Combined the cutting tool the main merit enhanced the production efficiency. If uses has 4 steps and ladders the drill bits, processes time probably to reduce 70%. Besides economical trades the knife time, the user also may from the engine bed knife storehouse position and in the reduced cutting tool cartridge which empties obtains benefits, the knife storehouse position which empties may cause the spare cutting tool to give while engine bed work to replace. Because the cutting tool quantity reduces, therefore may simplify the cutting tool the management, saves the expense. About combination cutting tool price expensive question, when computation should consider ntsbecause reduces and saves compensating which the administrative expense obtained arrives; Therefore, a special-purpose combination cutting tool can substitute the standard knife are more, should jump over early performs to use. In addition, in the processing quality aspect, the application special-purpose combination cutting tool also is advantageous, causes the engine bed the pointing accuracy no longer to be that important, for example more than stairs holes center complete in on the processing, the hole misalignment error also reduces, because the front drill bit played the calm role to the behind drill hole. At the same time, uses the operator, which the complex combination cutting tool requests the engine bed to have the corresponding knowledge, therefore should carry on training totem. Each kind of combination cutting tool introduced which from above may see, most combines the cutting tool aims at the special-purpose cutting tool which a specific application situation develops, therefore supplies goods the time to be long. How can reduce supplies goods the time, ntsguaranteed the product quality, Comet Corporation implements in 1996 to be easy special-purpose the project, with the aid of a CAD/CAM system, might carry on the simulation to each concrete work piece combination cutting tool according to the blueprint data. Until now, Comet Corporation combines the cutting tool30% sales volume is with this method development, supplies goods the time to drop from the average 8 10 weeks to only needs 3 weeks. 3 Combines the cutting tool the prospects for development At present the more and more complex combination the user approves cutting tool structure. In order to impel to combine the cutting tool the development and the expanded use scope, the cutting tool manufacturer while develops these cutting tools, must consider the user possibly meets all sorts of questions, seek solution, takes all sorts of measures, has the certain flexible including the development controllable cutting tool, develops the new coating technology, the cutting tool material and the geometry shape, for reduces the cutting tool cost, even may shift the cutting ntstool production base to the production cost low area produces But has the flexible combination cutting tool only to have in does not have to transform the engine bed or can smoothly connect with the control system time only then can promote; The new combination cutting tool and the processing efficiency related each factor, like factor and so on substrate material, coating material, geometry shape, all will be supposed to aim at the concrete processing object to give the optimization, will form the comprehensive superiority. At the sometime, because the non-cutting time saved enhanced these superiority degrees of utilization, obtained enhances the productivity the effect. This kind the enhancement cutting efficiency and the reduction on-cutting time synthesis application tendency, will impel combination cutting tool more widespread application. - Orlov P.
