The car makes cutting process systematic project and application

Be because cutting tool gave an issue,only? In real work, many people often have a kind of chronic thinking, in cutting treatment once appear unusual, considered as cutting tool to give an issue, work and solve measure in great quantities much also around move cutting tool undertakes, its were to spend a lot of energy and time however as a result, the reason still is not understood very, the problem is couldn't get solve thoroughly. Actually, cutting is machined especially efficient treatment is issue of a system, cutting tool is a link in this system only. In cutting treatment, the collective composition such as fluid of processes work semifinished product, equipment, cutting tool, clamping apparatus, cutting a system, the problem that cutting machines is the child under the many elements in this system and variable and integrated action. And, to at many enterprises character, this " system " not may only show is a working procedure or an equipment, rectify a manufacturing Jin however; And cutting tool oneself is an among them subsystem, include coating of material of blade of material of appearance of cutting tool structure, geometry, cutter hub, cutting, cutting tool to wait many respects a moment. Afore-mentioned all elements are together integratedly, precision of appearance of form of influence and the size that deciding a product, appearance, position, surface, treatment, and the any element in whole system produces change, can machine efficiency of quality, treatment and finished cost to produce an effect namely to systematic output. Cite the case of a very good understanding, in the past, although people has felt cutting fluid has effect to cutting treatment, but the general and auxiliary data in just also often regarding production as treatment its will handle. But present manufacturing practice tells people however, the cutting fluid that regards one of systems of whole cutting treatment as annulus is already important to such degree, fluid of Wu Ruguo cutting chooses down to improper or it is misgovern can cause production even cannot on the rails, cutting tool cannot be used normally. For instance, milling machines the requirement of short of of workpiece surface quality that come out, change of supplier of much home tool different improvement milling cutter still also is short of requirement, change finally after of machine tool main shaft, machines workpiece quality achieved a requirement, the real source that discovers a problem is absent cutting tool, however the other element in the system produced a problem. 2.

On broad sense " cutting processes a system " of main shaft of 　 machine tool jumpy, machine the vibration in the process, the dynamic balancing of cutting tool, the breed of cutting fluid, chroma, pressure and discharge, the preliminary adjustment of cutting tool, and of cutting parameter match etc, the result that can machine to cutting produces major effect, and the account that influence cutting processes a result is far more than these. Nextpage 　 machines efficiency to raise cutting, in recent years efficient cutting won wide application, but need to notice is, to the cutting treatment at automobile manufacturing industry, what true efficient treatment goes after is the tall cutting efficiency of only station machine tool not just, the tall cutting efficiency that begs Jin of implementation is full production even, what also pursue whole system namely is efficient. This arranges craft, appropriate machine tool equipment and efficient cutting tool reasonably with respect to need, scientific management and perfect process hierarchy of control and fast, reliable cutting tool supply content fluid department to wait. The station looks in this height, cutting processes this system bigger, it is the corporeal system that medium of device of the treatment that be mixed by treatment workpiece, treatment forms not only; The life control that still includes cutting tool, blade is ground, adjust, purchase the administrative system that supplies the composition such as management, cost accounting and control; Cutting parameter set and tone knife and build the technical system that grinds the composition such as the standard; Cutting database and the information system that cutting tool runs the composition such as software are waited a moment. Of cutting treatment system form 　 1.

Compositive element includes juice of machine tool, clamping apparatus, cutting tool, cutting, by treatment workpiece, handlers, etc. 2.

Each subsystem include quality of system of system of tribology of machining complex, cutting, cutting tool system, machine tool system, clamping apparatus system, cutting tool management, cutting to control a system, etc. 3.

The input includes to need the work semifinished product of treatment, each treatment asks to wait. What this should notice is, work semifinished product is systematic input, but it enters cutting to machine systematic after, become cutting to machine a part in the system again, the other variable in processing a system to cutting and output of cutting treatment system produce an effect. 4.

Output processes finished product namely, the treatment result of implementation, if machine efficiency of quality, treatment, finished cost,wait. 5.

Feedback and control are measured and control formed the influence that outputs pair of inputs (if pursue 1) , this is a kind of feedback. Feedback has make a present of of positive and negative to also have negative feedback, output the error that answers to the input, through appropriate feedback attainable correct in time, make output is worth convergence to the center that inputs a requirement, output otherwise be worth with respect to target of deviate of meeting all the more, appear into approved treatment reject. Graph since the development of the feedback of system of 1 cutting treatment and project of system of control cutting treatment and applied cutting treatment are a systematic issue, the viewpoint that can use a system only and method will analyse and be handled. Systematic project is a when nearly 30 years development rises burgeoning integrated course, be in again apply systematic viewpoint and systematic method to handle complex project, scientific research and manufacturing task. Ancient bronze mirror also lies at the theory of systematic project and methodological itself in research and development process, and its application machines a domain at cutting, the problem should reply and more a lot of is solve, need develops new theory and new method, have ceaseless exploration and effort. Project of cutting treatment system is attributive at systematic project this old course, but it is course of a when machine process application place to form in the light of cutting special branch, consequently a lot of methods will be place of cutting treatment field is peculiar. Become efficient treatment truly to make cutting is machined, want to undertake theory is discussed not only, more big batch of the end that wants treatment of cutting of base oneself upon to want to achieve, implementation and flexible the efficient treatment that turn this angle will have analysis and application, accordingly, the innovation of idea and method is indispensable. It is to be engaged in support of technology of technology program and design, spot and manufacturing management no matter, or is engaged in cutting tool design, cutting tool making, cutting tool sale, cutting tool application, still analyse solve the cutting that concerns with cutting tool to machine a problem, must set out from systematic viewpoint give the analysis reconciles definitely. This asks we have cutting to machine the knowledge of systematic project, understand each subsystem in this system, the method that uses systematic project obtains cutting to machine the integral solution of the problem. Method of system of Nextpage 　 application is analysed and solve cutting to machine a problem through handling systematic project, can use resource of limited labor power, material resources, financial capacity right way, solve cutting to machine medium difficult problem. 1.

The integral sex of the system of ① of 　 of systematic spy a note of the ancient Chinese five-tone scale that meets cutting treatment: Cutting treatment is a whole system, because this is solving the conception that the system must build when the problem, consider its whole sex. The dependency of ② system: Cutting treatment system is the system of a many variable much input, its are immanent and departmental cent is linked together cheek by jowl and have interact, need is analysed on the foundation of integrated consideration and solve cutting to machine a problem. The dynamic sex of ③ system: Cannot see a problem still, and need to undertake dynamic analysis. Pay attention to the interface of each subsystem and connection, understand each subsystem deep and follow the objective law that its run, make the system is in Wu Shou to accuse state hard. 2.

Hold tigidity of ① of methodical viewpoint 　 from beginning to end: Show machine tool, clamping apparatus, workpiece and cutting tool are whole systematic tigidity, the tigidity of the machine tool itself with isolated and rather than. ② is jumpy: It is cutting tool outfit what go up in main shaft is jumpy, is cutting tool itself not only is jumpy; It is a machine tool the trends in athletic process is jumpy, is the machine tool stops the static state in the process to beat not just. ③ efficient treatment: Those who emphasize whole production Jin is efficient, is individual working procedure or only station equipment not only is efficient. ④ makes cost: Also be integrated cost of the system, the comparison that undertake falls in same caliber and condition, be from overall the cost with long-term balance. 3.

The common cause that divisional influence system changes and system of treatment of special account cutting serve as a dynamic system, be in all the time among them producing all sorts of change, look from the viewpoint of systematic project, the cause that affects its to change can be divided for common cause and special account. Common cause is the element of the inherent random change in the system, and special account is not systematic place is inherent, but the apparent change that can cause a system to output. The sketch map that changes along with time from cutting tool life is visible (graph 2) , cutting tool life produces fluctuation to fluctuate around a certain average so, the cause that causes this kind of tiny wave motion is a system common cause, but if life of cutting tool of after of period of time is abrupt,lengthen, this is put in some kind of special account necessarily. Graph the sketch map that life of 2 cutting tool changes along with time at this moment, must seek this kind of special account and take corresponding step, perhaps make cutting tool life restores original rate, or was to discover some kind of advantageous element, should try to consolidate its come down, become the inherent factor in the system, prolong cutting tool life thereby, reduce cutting tool cost. 4.

The fluid of cutting of influence 　 ① that takes cutting fluid seriously to process a system to cutting applies mediumly in machining very general, but the value that a variety of effect such as the lubricant, refrigeration that its have cut treatment to Wu Qie is not well known. ② knows the tribology character of cutting tribology system, understanding chooses the importance of right lubricant kind, method of lubrication and lubricant medium. In the process control that ③ machines in cutting, must reach cutting fluid its lubricant means includes cutting fluid breed, chroma, cleanness to spend, PH value, discharge, pressure as the process control parameter fathers impose control, such ability ensure the cutting that wins a demand machines function and treatment quality and tall manufacturing efficiency. 5.

Cutting tribology has applied the basis to guide cutting tool takes a form guide a cutting tool made full use of tribology principle, the boring that its ably application is versed in at accurate Kong Jia and bore with a reamer cut cutting tool to go up. Below good working case, cutting tool guides already did not machine the surface to be contacted directly with workpiece truly, truly effective is cutting tool guides already processed an oily film between the surface with workpiece. And this oily film whether form, stiffness of its oil film how, it is this kind of belt guides the key with a cutting tool successful job. So, of this kind of cutting tool guide the design mixes a structure make have a lot of special demands, very tall also to the requirement of cutting fluid. 6.

The application of coating of cutting tool surface has systematic condition to think commonly, coating application grows advantageous Wu Yan cutting tool life in cutting tool surface or improve treatment efficiency, also be coating does not act well only below unfavorable circumstance just. But actually, the application of coating of cutting tool surface has systematic requirement, also ask to process some kind of data namely, certain cutting tool base material and certain exterior coating need to match with the working requirement photograph such as certain cutting parameter, if the choice is undeserved, produce negative effect likely. Nextpage 　 　 7.

Those who master cutting tribology system match coating of surface of material of deputy sex cutting tool, cutting tool to had chafed in cutting Cheng Zhongcun is in with be machined of the tribology system of workpiece material compound deputy sex problem, need radical solves the comfortable problem matching a gender between material of different and phyletic workpiece and cutting tool material and exterior coating material at cutting tribology, in order to choose right cutting tool stuff and corresponding exterior coating. The system of production cost controls 　 1.

In paying close attention to craft to plan to design, one-time investment and long-term sex make the relation 　 ① between charge notice to will make maintenance of cost of the equipment depreciation in charge, manpower and public motivation, cutting tool, equipment and spare parts, chemical use up wait for operation expenses to connect unified consideration and analytic processing problem. The adoption of the discretion of charge of ② cutting tool and new cutting tool, new technology, new technology, new material is close together and relevant, with cutting tool purchase, content shedding, adjust, long grind, control of cutting tool quality, cutting tool is optimized reach the many sided such as cutting tool management to connect cheek by jowl. 2.

The ① of 　 of work of cutting tool field that takes a project seriously to plan to invest level highly in recent years working practice and domestic and international experience make clear, tens of thousands of yuan knife has a value to affect a value possibly millions of yuan the play of the efficiency of equipment. ② notices one-time equipment and cutting tool investment and long-term sex cutting tool use up the relation between charge. Some projects may plan in the project season restricted installation cost, used costly cutting tool or unreasonable cutting parameter however, cause cutting tool life weak point and long-term cutting tool spend cost exorbitant, need integrated balance. Level of ③ technology program decided the production cost of stage of production and cutting tool charge greatly to the design of cutting tool and arrangement. 3.

Handle equipment of ① of 　 of several main concerns choose with cutting tool choose the concern between; The relation between ② current design and long-term consideration; The relation between ③ program crop and actual output wave motion; ④ lessens the impact between facility amount or investment and craft rationality; ⑤ cutting dosage increases the concern between the cutting tool loss of life with the likelihood; Installation cost saves ⑥ to raise the concern between with cutting tool charge; ⑦ is flexible turn the concern between degree and treatment efficiency. 4.

Technology program needs to get used to systematic condition to use what kind of technique, equipment, cutting tool to wait to reach its with crop fluctuant circumstance is close together and relevant. The viewpoint that processes systematic project from cutting looks, cannot say simply to use machining center machine tool it is good, good to still use private plane, perhaps use some kind of equipment to had been combined, the key should treat the integrated condition of the system of a composition, and whether do its get used to surroundings condition, because good technology program is in the under certain circumstance,do not suit likely below another kind of circumstance. Important is, the circumstance of mutual to this kind change and its correlation undertake analytic study, with this directive technology program and design. 5.

What project program level needs to try to explore to cutting tool durability and the control of use cost is, if where,the program design phase of the project is chosen to the design of cutting tool try more active management and control, put forward after of project put into production to be opposite to equipment supplier and tool supplier cutting tool durability and the main demand that concern use cost, the cutting tool cost that will produce to after of put into production and the program level that make an item have forecast and control. This will raise new project to carry out the technical economic benefits of after considerably. Epilogue cutting treatment is a complex old system, want to realize true efficient treatment to must use the method of systematic viewpoint and system. Also because of this, we cannot isolate the problem in cutting treatment system rift of the ground, dormant ground, cent comes to the ground look upon and processing, need to break professional dividing line however, attention machines the many complex element in the system and variable to cutting. On one hand, we should understand the professional characteristic of each subsystem itself; On the other hand, need is searched and still discover the mutual connection between each subsystem and interaction, each subsystem is in-house the mutual connection between each element and interaction, know the effect that their interact outputs to the system, master the relation that restricts each other between certain variable. Can imagine, the progress that contemporary car makes brings new task ceaselessly, appear more difficult treatment material, the treatment quality with higher demand and treatment efficiency, and the finished cost that has competition ability more. Face these challenges, the application of systematic project method will provide efficient way and scientific means, what obtain cutting to machine plan and function of cutting cutting tool thereby is comprehensive optimize, let the new issue be readily solved that appears in cutting treatment, the cutting that realizes ideal machines systematic output. Afore-mentioned a variety of innovate add of conduce Wu Chi, enhance the core competition ability of the enterprise. CNC Milling CNC Machining
