Especially lesser job shops often needs to consider a machine tool to should obtain issue of what kind of automation water equality after all more. as a result of this one reason, these job shops always take the kind that raises workshop automation level stage by stage. Company of graph 1 Pfeifer Industries is inside the workshop with a clean and bright, clean lamplight operation, but have two employee only. Resemble other and small-sized workshop in that way, this company uses the means of successive, realized automation to produce stage by stage to small-sized with large manufacturer character, the automation that uses whole set machines equipment to be able to reduce manufacturing cost already, can improve flexibility of manufacturing efficiency, production and product quality again at the same time. Especially lesser job shops often needs to consider a machine tool to should obtain issue of what kind of automation water equality after all more. as a result of this one reason, these job shops always take the kind that raises workshop automation level stage by stage. Be located in Yilinuosi the Pfeifer Industries company of city Naperville city was offerred for course of study of person of the same trade in the light of a when solve this problem famous case. The workshop of this two individual operations has a Che Xi to machine a machine tool only when practice, use the material on manipulator of dragon door type, soon this workshop begins to use automation operation and spare parts to be measured randomly. The kill that such doing, not only the manufacturing efficiency that improved a machine tool, and realized nightly and unmanned operation, the treatment quality of the spare parts in assuring to turn production in nobody (graph 1) . Pfeifer industry company is engaged in the treatment of component of mechanical power drive technically. 2004, company happening weighs revolution, mix by Mr Brian Nass of the company after this familial a friend Mr Jim Donovan decides to buy this next workshops. Mr Nass has necessary administrative experience and treatment knowledge in manufacturing business side, on the other hand, mr Donovan has the experience of downstage operation, wait like management of items of an account and engineering design, they struggled 15 years jointly in Pfeifer industry company the time of above. Mr Donovan says: "The key that I know to gain a success depends on making the workshop develops ceaselessly expand, as far as possible the moving efficiency that apace improves a machine tool. Produce workshop and distribute company as profit of a seed, all sorts of title that Mr Brian and I must assume place of company of management Pfeifer Industries. " original, new owner can be mixed in existing technology only this company expands on equipment foundation. However soon, to satisfy the client's requirement, manufacturing technological equipment needs apparently large-scale rebuild. The workpiece breed that they machine is various, production lot is small, the time of card of tone trial assembly that the workshop needs to quicken workpiece and improve manufacturing efficiency. This workshop has two parallel product line, use at the treatment of different workpiece, the spare parts that if have,comes from a racing bicycle to produce business client and 1000 batch that come from an industry client produce a part. In the past, every time Mr Nass is engaged in producing the job on a product line when, another operation personnel always does not have a thing to be able to be done. To seek more effective solution, this workshop invests machining center of turning of the NL2000 that purchased company of aircraft of a dark essence SMC again, configured device of the makings on dragon door type. Such, realized the automation treatment of the spare parts through device of the makings on this, reduced the operator artificial intervention to the machine tool substantially, make Mr Nass can run two product line at the same time. After Pfeifer company is using new machine tool managing many time, it is with the treatment of some workpiece now exemple try to explain: This is a timing leather belt that becomes with steeliness of 12L 14 carbon annulus. The craft previously is above all the one aspect of the matter of turning treatment spare parts, use handiwork general next its debus, after new outfit gets stuck again turning machines another end, send this work to machining center to undertake milling is mixed again auger cut treatment. Anyhow, the time that this workpiece turning machines needs 3.

25min, next again milling is machined 4.

The time of 13min. Graph the dimension that 2 installation check the obstruction computation that the system can shed through measuring cooling fluid to give a part in the hydraulic pressure on the machine tool. According to the view of this manufacturer, this device was craft stability to make enormous contribution, because it can pass process designing, adjust the deviation of cutting tool or again cutting, assuring a spare parts to ask to machine company of graph 3 Pfeifer to be engaged in mechanical power drive technically according to norms is the treatment of component, detailed sees the part that shows in the graph. The turning machining center that this workshop matchs to have unit of the makings on type of new-style dragon door and hydraulic pressure survey a system, make the productivity of its spare parts from machine 87 to increase 252 everyday however, the layshaft that using NL2000 machine tool and inside after buy milling machines electric machinery, the workshop can be in now 5.

The treatment of entire part is completed inside the time of 33min, treatment cycle shortened about 28% . In addition, because the machine tool can expect to be pulled on machine from dragon door type automatically,send beforehand the good stuff with good cut, because this Mr Nass is horary now,the time that needs to cost 10min only stands in the job before turning machining center, compare with the craft photograph previously, a lot of more managing time, this equipment needs somebody to attend all the time previously. This makes he has more time to attend the treatment circumstance of other workstation. After new machine tool wins successful trial, the Pfeifer company demand to satisfy a client better, raised the automation level of the machine tool further again. Mr Donovan says: "Besides treatment when beyond leather belt annulus, a lot of our clients search come to come, ask we machine the complex part of high accuracy for them, they gave other firm treatment the package outside this kind of spare parts in the past. We hope to develop machine tool of dark essence machine adequately to offer our advantage, also can satisfy their requirement, in the meantime, we still can produce our pillar part product. " the company still is in nightly and executed nobody to change producer style on the weekend. However, be in nightly in having lamplight exercise process, because do not have a kind of method can the treatment quality of monitoring spare parts, of cutting tool wear away 0 what can make the treatment precision public errand of workpiece exceeds a regulation.

01mm(0.

0004in) . To solve this one problem, pfeifer company found company of dark essence aircraft again, become the first United States company that uses monitoring of manufacturer hydraulic pressure to survey a system. The working principle of this measurement unit is similar to a tensimeter, but use high-pressured cooling fluid to replace gas. Installation turns in the machine tool an outlet on the tower, can insert a spare parts in, high-pressured cooling fluid passes the little gap between spare parts and outlet below pressure extruding. The software on the machine tool can shed obstruction according to measuring the cooling fluid of earning, computation gives the measure of the spare parts. According to the view of this factory, the measurement of the spare parts needs 3s only, the repetition that its measure precision can amount to 2µm(0.

000077in)(graph 2) . Be in allegedly nightly without lamplight work requirement falls, this working effect that measures a system is very good. Its reason is very simple: If the external diameter deviate of bore diameter dimension or spare parts booked tolerancepublic errand precision, this system can slant to buy is measured or choose a new cutting tool through adjusting automatically, make its maintain with the precision level that reachs a requirement. It also can pass process designing, again cutting machines a spare parts, administrative statistic quality is controlled (SQC) and the time interval according to the regulation measure a part. Mr Donovan says, by the treatment of tool wool blank that changes quickly, cheap gauge is particularly useful to Pfeifer company. "We can use gauge easily to measure us the dimension of each spare parts, the commutation between batch and change cutting tool and like running corrective program simple. And the most important is, be in nightly when working without lamplight, the contact bougie that I need not worry about dollar of value 12 000 can happen rupture. " besides treatment cycle shortens besides, the combination that expects device and hydraulic pressure survey a system on dragon door type is used, make the potential handling time of Pfeifer company increased one times above. This workshop can stabilize ground treatment to produce 252 parts everyday now, and can produce 87 parts only everyday in the past. Manufacturer of great majority of no less than in that way, the majority that fixed costs made up for Pfeifer company is overall cost, its increase the productivity of 3 times to make those fixed costs of this company arrive dispersedly in many spare parts approximately (graph 3) . The positive result that accordingly its obtain actually is, the manufacturing cost of every spare parts reduced 70% above about. Mr Donovan says: "After using new system, the biggest challenge that we face is, how to make our conveyer is in the condition of full load. This is a place that has development outlook extremely.
