E.F.Bavis develops in-house aircraft process capability

F.

Bavis is one is engaged in bank, pharmacy, cafeteria and other industry place those who use is pneumatic the banner manufacturer with mechanical drive system, this company devotes oneself to metallic thin plate to make all the time for years, solder, plastic shape, vacuum shapes and wiring harness assembles the development that waits for craft. Machine treatment is one of newest workmanship that this company introduces interior, although this company is returned at present,the form of the bag completes this kind of treatment beyond the meeting. "The opportunity that has to belong to his job shops besides OK and economic cost, still can help a company maintain the level of goods in stock that runs easily. When production cost and purchase cost to differ not a long time, the form of completely OK and in-house production replaces the part that purchases small lot. In addition, when if drive system is designed,need uses custom-built part, the company also won't be immersed in deserted goods in stock in overmuch predicament. That is to say, we can retain on at hand certain raw material goods in stock is pressed need to undertake machining. Additional, retain oneself process capability still can be on guard the abrupt close down of the supplier, or component demand is too little so that use outside bag business cannot obtain the condition such as reasonable cost effectiveness. " the say of deputy total Mike Brown that produces a section. E.

Bavis company founded his job shops, from now on, this company discovered have a lot of profit that process capability place brings in-house machine to expand machine process capability Mr Brown joined E 1984.

F.

Bavis company. As time elapse, this company goes to business emphasis move gradually on the production of drive system. Nowadays, e.

Bavis already was the banner supplier of long-range drive system and relevant equipment, it is exclusive a company that can supply equipment of drive of solar energy power supply to specific applying. After taking over the job as production vice-president when Mr Brown, he begins put forth effort the engineering capability at adding a company, with better the product line of outspread company. 2002, made them finish machine tool of the first CNC of company in the supplier problem that produces on a kind of plastic component purchase, milling machine of a Haas TM-1, turn relevant task to be finished for interior. This kind of plastic mould uses ply for 0.

The polyethylene material of 75in is made, grow 12~20in, wide 4in. Mr Brown entrusts a lumber to machine business a future life to produce this part at first, this enterprise uses a hollowing planer to give many parts from the treatment on chunk plank. But the tigidity as a result of this hollowing planer is finite, the component size that production of this company place comes out is not exact and the surface is bright and clean degree poorer. After this, the next supplier that Mr Brown finds because production lot is lesser and the bench clamp that this company place uses can be used at workpiece clip to hold only, its produce cost to be gotten high unusual. Final, mr Brown used custom-built clamping apparatus to be in buy the treatment that these parts have on milling machine newly. He designed a kind to be used at bore and the clamping apparatus that bore hole and the clamping apparatus that cut component periphery share with Yu Xi. Inside 6 months, this task called in the CNC milling machine of 19000 dollars invests. Very fast, this company purchased machine tool of the 2nd TM-1. bore / bore hole clamping apparatus installation is on a machine tool, circumjacent milling clamping apparatus installation is on another machine tool, can let same operator attends these two machine tools at the same time.

Bavis company still purchased lathe of a CNC and machine tool of the 3rd TM-1 finally, the 3rd TM-1 provided library of a knife, use at mould treatment and batch production work at the same time. Design special fixture Mr Brown still made exercise design fixture for whole interior. Be changed to accelerate the task and simplify clip outfit, he locates in every need the center of milling machine workbench of clamping apparatus all installed a firm fixed position to sell base. When clip is installed, handlers needs to call code of system of coordinate of workpiece of a G54 only (the center that is used at defining fixed position to sell) , call code of coordinate of this locality of a G52 next, form a specific correspondence at place the provisionality workpiece deviate of clamping device is measured. Carry this kind of kind, handlers need not appoint the position of new clamping device, and numerical control program can duplicate and add to each milling machine, make these components OK be produced on any usable milling machine. Besides these relative to relatively simple clamping apparatus, mr Brown still was designed a few otherer more complex workpiece clip runs unit, chuck of consistent stage vacuum and one matchs those who have pneumatic motor to rotate type workbench, with Yu Rong accept passes the long pipe that zincous oxidation processes, but these pipe dislocation so that 180 ° carry out drilling operation in two side. Mr Brown says, when component amount opposite more or when need has long-term production, the investment to clamping apparatus is worthiness. The batch production part that used bench clamp exclusively is lid of end of a kind of steeliness. But, this bench clamp serves as a kind of specific clamping apparatus only, be not hold component itself with Yu Ga. This clamping apparatus is held by clip in custom-built gate Neibingke accommodates 2 end to build. Fixed position is sold conduce to in machine treatment lid of end of process lieutenant general is secured. After machining circumjacent outline and back side notch, handlers can get off this clamping apparatus from bench clamp, retroflexion got on its clip again in the past, the radius limits that can carry a lid to every thereby undertakes milling. This one working procedure can complete part of two finished product inside 3min, and the cost that is used at making every part is 3 dollars, and the quote of exterior treatment company is every 5 dollars. Control in-house output Mr Brown to admit, process capability still is in the machine of the company moderate level, also do not have the expert that any employee are machine treatment respect. But go up in this foundation, this company still can make full use of process capability mixes its machine relevant production resource, design new product around his internal production process. On the other hand, the real cost that interior makes must can decide at any time, because some moment can appear,use outside supplier instead more the circumstance with sound economy.
