How to raise equipment actuate rate

Raise the equipment actuate rate of machine treatment transfer matic, it is the objective that every enterprise pursues. How to use significant step and method to raise the actuate rate of equipment, every enterprise has his working experience. The article at this point of the target carry out, through " the attention of the settlement of the analysis of the participation of TEAM, problem, bottleneck, element, perfect with summary run " the train of thought that waits for a few respects to solve a problem, discuss how to achieve the goal that raises equipment actuate rate. In the production of car motivation assembly, engine, gear-box machine machines the equipment actuate of transfer matic to lead on any account, can affect the production cost of the production program of the enterprise and engine, gear-box directly. If where,the design of primary facility maintains design ability to keep abreast of on ability the actuate rate that one pace raises equipment, became the content that supports branch and administrator challenge to the spot. What can mirror equipment actuate to lead on any account truly is to be in when product line is run 3 classes. The maintenance that affecting equipment actuate to lead the biggest factor of on any account is equipment and maintain time and time of cutting tool exchange. 2 one class, equipment when running maintain reason besides instant maintenance, until the last moment when, relevant personnel still can use equipment to stop TNPM is done when machine (complete production safeguards a standardization) , PM (production is safeguarded) . 3 equipment actuate when running are led, just be pair of spot management department and supportive staff the real test of real capability and report. Want to raise it to must take all sorts of adverse factors of rate of actuate of equipment of the influence in solving bottleneck working procedure. The participation of TEAM should raise treatment transfer matic a certain working procedure or labour actuate rate, need by program, maintenance, cutting tool, qualitative protect, purchase, the TEAM that the personnel such as chemical, production comprises will share analytic problem jointly, solve a problem. Wait by engineer, technician, senior technician compound model storm of personnel composition brains group, reasonable the knowledge that uses each member and skill cooperate in coordination. Pass the combination of different role, pertinent question is in charge of by relevant personnel, other personnel is collective and active support, mutual trust, complementary, produce the optimal effect of the group, in order to achieve the result of get twice the result with half the effort. TEAM builds CIP (improve ceaselessly) conference form, build regular meeting system. Carry out adequately cooperation and cooperate, relevant personnel reachs time analyse to solve to new issue, old issue dogs summary, achieve common goal finally -- raise equipment actuate rate. The analytic machine down time of the problem includes time of machine tool warm-up, TPM (overall production is safeguarded) the time, breakdown time, time that change a knife, workpiece measures time, machine tool to wait for expect breathing space of latency time, jockey, equipment adjusts maintenance time to wait. Solving influence equipment actuate to lead optimal result is the adverse element that can lead influence equipment march is solved entirely, machine down time control is inside lowermost limits. Because equipment uses fixed number of year different, run manufacturing number JPH of different, order (Job Per Hour) crop is different, analysing influence actuate to lead the means method of main reason also is different. 1.

Analyse the continuance of equipment machine down time as use time, odd with respect to equipment itself character, the machine down time that affects equipment actuate rate is " tub " curvilinear process, if pursue,1 is shown. Tub outline curve stops machine rate curve on behalf of equipment, the end on 2 edges reachs tub from beginning to end bottom curve tilts, stop machine rate on behalf of equipment namely tall. From the graph 1 in knowable, as the addition of use time, the machine down time of equipment can produce the change of 3 phase, namely: Equipment is adjusted period, equipment is certain ageing of fixed, equipment wears away period. Graph 1 equipment malfunction and the relation curve of use time 2.

In assisting preparative influence to be produced actually, because some working procedure assist time to grow, if measure workpiece to await, the frequency that change a knife the frequent, time that move a knife slants long, stock carries the account such as archives, meet those who cause rate of working procedure actuate drop, the influence fixes the actuate rate of a product line. Serious when, still can become whole bottleneck that machines a line. The settlement of bottleneck uses 3 phase in the process to should adopt relevant measure in equipment, reasonable the actuate rate that raises equipment. Those who be like equipment adjust period, can pass those who sum up a gender to stop machine analysis, lead monthly to evaluate to the actuate of transfer matic, will get equipment actuate to lead small account. Sex of this kind of phase stops the analysis of machine, can understand cause adjust the bottleneck that stops machine period to be versed in reach a reason. Stabilize in equipment period, can pass those who build problem of of all kinds breakdown to solve guidelines, the measure standardization that removes trouble, achieve through maintenance shorten the time that removes trouble. Wear away in equipment ageing period, the metabolic trend of the reasonable arrangement that adopts PM and data of product part dimension dogs, the adjustment that discovers seasonable arrangement time makes good equipment in time and safeguard. Restrict theory to think: Product line is machined to go up in, the actuate rate of bottleneck working procedure decided the actuate of whole product line is led. Accordingly, in actual production, we should use finite charge and labor power to the transfer matic working procedure that needs to rise most, solve actuate to lead product line working procedure of lowest, in order to raise the actuate rate of whole transfer matic. Reason raises the actuate rate of equipment, where is the bottleneck working procedure that should consider to make a product line above all to be in? Look for bottleneck to be versed in from bottleneck working procedure again. The graph is shown 2 times for month of Xian Mou of cylinder body of V6 of plant of assembly of current motive force the actuate rate monthly of each working procedure analyses a case (Chanbansheng is produced) . The actuate of some month before each working procedure optimizes line of graph 2V6 cylinder body leads Nextpage to be analysed according to monthly, bottleneck working procedure is OP100, its actuate rate is 49.

17 ％ . Next, spread out an analysis to OP100 bottleneck working procedure, the bottleneck that analyses this process is versed in reach a reason. According to the analytic result of the problem, increase the TEAM staff that equipment actuate leads, list through brains storm the short-term measure that solves a problem reachs long-term measure, build what solve whole treatment product line back and forth " gully " plan, achieve finally " Campagna " the train of thought of good position. Carry out finally achieve numerous " gully " become slowly " upland " ; Again " upland " become gradually " Campagna " , the incline to of analytic data height that makes whole actuate that machines product line is led thereby at same horizontal. According to the monthly analysis of OP100 working procedure, auxiliary time grows the bottleneck that made whole process. From the monthly of OP100 working procedure analytic case looks (place of the 3a that be like a graph is shown) , before 4 machine down time is long main reasons are: Breakdown time, equipment warm-up time, CMM (3 coordinate) 37 what measured latency time and tone knife time to take an order time.

51 ％ . Graph time allocation compares the monthly that working procedure of 3 pairs of OP100 optimizes around · breakdown time is occupied 12.

5 ％ . Belong to equipment greatly the probability that sure conference appears and maintenance technician solve the ability problem that eliminates breakdown. Time of · equipment warm-up is occupied 9.

38 ％ . This working procedure 07 left labour it is to machine crankshaft to stop the work that chooses a side. Stop it is quite important to push positional measure in cylinder body, tolerancepublic errand small. Because be heated is adjustable,machine tool supplier is solving main shaft at the outset and generation stops when the positional dimension out of tolerance that chooses a side, use electric heat club to heat the method of main shaft lube will accuse to check the positional measure that pushs a scale changes. Heat when main shaft lube when certain limits, the heat of main shaft is stretchy also tend the smallest span, this kind of method assured the quality of the product on certain level, but the warm-up time of lube of the main shaft before be being machined everyday needs 45min. · CMM measures latency time to occupy 9.

38 ％ . This working procedure 6 labour, 7 labour two orders require treatment cutting tool move a knife, after moving a knife every time, all need to be measured with 3 coordinate, two labour measure time to need 45min left and right sides every time. · OP100 working procedure is finish machining working procedure, the demand of the skill that move a knife of finish machining working procedure is high. Because be put in jockey mutual the time changing a knife between and change a knife difference of percent of pass is big wait for an element, make the time that move a knife average occupy 6.

25 ％ . To raise the actuate rate of OP100 working procedure, TEAM relevant personnel through shortening the auxiliary time of OP100 tackles key problem solve. Relevant personnel uses converse thinking to allow 07 left worker worker above all main shaft is in the job below room temperature condition all the time, reduce main shaft the span of stretchy coefficient, assure to stop thereby the treatment precision of dimension of the position that choose a side, namely: By electric heat club lube of warm-up main shaft controls main shaft lube of main shaft of refrigeration of condenser water of stretchy quantity instead. Cooling lube makes the adjustable capacity of main shaft assures to stop inside the least scope the positional dimension of the treatment that choose a side, the practical effect after its transform: · goes to work formerly everyday the ability after equipment needs warm-up 45min can be produced normally, become go to work can switch on the mobile phone machine eligible spare parts; · machines a process formerly normally in, the adjustable quantity change of main shaft is in 0.

06mm left and right sides, and the adjustable change of the main shaft after transforming is in 0.

037mm, contractible 38.

33% . Stop the Cpk of dimension of the position that choose a side is worth by 1 the left and right sides rises to be more than 1.

67. In the meantime, solved CMM to measure the issue with long latency time through increasing a hand to move check to provide. In eventual actual production, dimension of cutting tool of quality of knife of attune of the skill moving a knife through raising jockey, promotion, control, reduce the time that repeats tone knife to wait, reduced the auxiliary time of OP100 working procedure substantially. The waste that OP100 working procedure assists time through decreasing, adjustable to main shaft control, increase the hand that follow a line to move check to provide, the skill of the technical ability changing a knife that enhances jockey and maintenance technician trouble removal rises, the treatment part time that a number can increase 110min (if pursue,3b place is shown) . Press metre computation, effective utilization rate raised machine tool of this working procedure 23.

11% , make bottleneck mouth became expedite way (if pursue,4 are shown) . The rate of with whole product line some month of actuate after working procedure of OP100 of line of graph 4V6 cylinder body is optimized compares what actuate of OP100 working procedure leads to rise, the bottleneck that let OP70 working procedure make whole treatment line is versed in. At this moment, recycle solves the method of OP100 working procedure, basically stay machine matter through what the record analyses this process, solve OP70 of bottleneck working procedure. After the actuate rate that needs OP70 rises, will improve OP40 process again, rise with achieving the actuate of whole transfer matic finally to lead. Perfect the equipment actuate rate that machines product line with summary machine, because process the form of product line those who process a product is different, different, the on any account that so actuate leads is put in certain difference. We can machine the adverse element that line actuate leads through eliminating an impact ceaselessly, gradually perfect drop device the method of a variety of breakdown, eliminate the waste of auxiliary time, build easy cost spare parts plans a system, answer ability of the member that foster backer quickly, those who extend rationalize proposal is complete member participate in and carry out ceaselessly etc, the square side side that leads to affecting equipment actuate builds reliable technical basis, to shorten maintenance time has reliable technical support. The improvement that passes CIP phase sex works, sum up the gain and loss in the job, the excellent job method that extends this product line is drawn lessons from for other product line, absorb the advanced means method that actuate rate raises on other product line and the experience that oneself do not have, achieve perfect with summary benign run. Actuate of equipment of machine treatment transfer matic leads rise, not be to want to rise how to much can achieve, it needs fibrous root occupies the actual condition in production, make full use of the action of TEAM, adopt the analysis, tentative idea, method that solves a process, the form that praise highly improves ceaselessly, what rationalize suggests is ceaseless carry out, improve standard of quality of cutting tool, equipment, semifinished product, perfect operation to wait, in the actuate rate that already thought impossible condition comes down to improve facility. In carry out in solving the process that raises rate of actuate of machine treatment line, affect the adverse factor that actuate leads through paying close attention to person, machine, makings, law, annulus to solve.
