FTQ_Translation一次下线合格率

1、first time quality,2,first time qualitytraining module,training objectives 培训目标: to understand 理解 what first time quality is 什么是一次下线合格率? why it is important 一次下线合格率的重要性 why we need to measure it 为什么需要对一次下线合格率进行测量? how to calculate it 如何计算? what the ftq deployment process is 怎样进行ftq? what the basic q

2、uality tools are 基本质量工具是什么? how to apply the quality tools 怎样运用基本质量工具? what the deliverables are that each plant will be responsible for monitoring and reporting 每个工厂应该监控和汇报什么?,3,first time qualitytraining module,what is first time quality? 什么是一次下线合格率? first time quality is a measure of the number o

3、f pieces rejected in a manufacturing process versus the total number of pieces attempted 一次下线合格率是测量制造过程中不合格品数与总产品数的比值.,rejects,4,first time qualitytraining module,why is ftq important? 一次下线合格率的重要性 because if we dont make good parts the first time, we have to inspect in quality 因为如果我们第一次没有生产出好的产品,我们就

4、必须进行检验. we know inspection is at best 85% effective 我们知道检验至多只有85%有效. therefore, anytime ftq is greater than 0, we are dependent on inspection to protect the customer 因而,如果任何时候一次下线合格率大于0,我们都需要依赖检验来保护客户. to reduce manufacturing costs 降低制造成本 to eliminate waste through the value stream and meet customer

5、 requirements (take time) 通过价值流和满足客户要求来消除浪费.,5,catch defects,filter,inspection misses some defects 检验会遗漏一些缺陷,defects not caught 漏网缺陷,voice of the customer 客户的意见,problem问题,d,d,the role of inspection,d,inspection is like a filter 检验好比一个筛子,6,1,2,catch & count defects 抓住并计算缺陷,react to alarm limits 超过警戒线

6、的反应,follow reaction plan 执行反应计划,voice of the customer,the role of first time quality process,reaction plan,zero defects forward,7,analyze data understand defects and decide the order of priority: 理解缺陷并决定优先次序 assign problems to cross-functional group: 向跨功能小组提出问题 select and plan the improvement: 1.rig

7、ht information 2.right cause 3.right timing 选择并计划改善问题 正确的信息 正确的原因 正确的时间选择 fix the biggest problems first: 首先找到最大的问题所在,responsible team works problems,defect 1. - 2. - 3. -,hour glass,the role of first time quality process,4,3,2,3,2,2,1,1,1,1,8,first time qualitytraining module,why does ftq need to b

8、e measured? 为什么需要测量ftq main reasons 主要原因: it is the first signal that a process is out of control 它是过程失控最先发出的信号 it allows us to respond to problems internally before they reach our customers 它使我们能够在问题到达客户之前内部先对问题作出反应. it measures improvement from corrective actions implemented 通过执行纠正措施后来衡量问题改善的情况. i

9、f we dont fix our quality problems internally, we will never be able to fix our external customer issues 如果我们不能在内部找到质量问题,我们就不能确定外部客户的问题.,9,first time qualitytraining module,how is first time quality calculated? 如何计算ftq ftq is reported in parts per million (ppm) defective ftq反映每一百万个产品中的缺陷产品数. it can

10、be measured at any step in the manufacturing process where parts are rejected 能够在制造过程的任何一步测量ftq. it is calculated by counting the number of pieces rejected versus the total number of pieces attempted 通过以不合格品数除以总数来计算. the total number of pieces attempted includes all good pieces produced plus all pie

11、ces rejected 总的产品数包括所生产的合格品数和不合格品数之和. pieces rejected are all parts scrapped or reworked prior to usage by subsequent processes. the actual calculation looks like this: 不合格品数包括所有报废和经过返工后合格的产品数. 公式: number of pcs. rejected total number of pcs. attempted 不合格品数/总产品数x 1,000,000 = ftq ppm,x 1,000,000 = f

12、tq ppm,10,first time qualitytraining module,how is first time quality calculated?如何计算ftq? an example at the cell level: cell “a” has six operations a单元有6个操作工序 reject data is collected at operations 3 and 6 第三和第六工序收集到不合格品数据 cell “a” produced 1040 good pieces during the first hour of production. 第一个小时

13、a单元共生产好品1040件 at op.3, 28 pcs. were rejected. 第三工序发现28个不合格品 at op.6, 16 pcs. were rejected. 第六工序发现16个不合格品 what is the ftq in ppm for cell a? a单元ftq的ppm是多少? 28 + 1644 1040 + 28 + 16 1084,1,2,3,4,5,6,= x 1,000,000 = 40590 ppm ftq,28,16,tally sheet,11,first time qualitytraining module,what is the first

14、 time quality improvement process? 什么是ftq改善过程? ftq process defines a common process to be used by all delphi e & c manufacturing plants to meet the business plan requirements and drive defect-free manufacturing ftq是delphi e & c 工厂常用的以达到商业计划要求和无缺陷生产要求的一个方法. the ftq process defines ftq定义: process step

21、ning module,process step 1 第一步 define reaction plan and alarm limits 定义反应计划和警戒线 you have to start someplace alarm limits must be based on current process reject data or available data from mq2, run at rate, historical data, etc. 警戒线必须基于在当前工艺下生产的不合格品数据, 或源于mq2, 按节拍生产,历史数据,等. alarm limits must be stat

22、istically calculated 警戒线必须进行统计计算. alarm limits must be communicated to operators so they can react 警戒线必须与操作人员进行交流沟通. if alarm limits are exceeded, there must be a reaction plan to implement 如果超过警戒线,必须有一个可执行的反应计划. the reaction plan must clearly define what actions are to be taken 反应计划必须明确所需采取的行动.,def
