Hellow I need help for an assignment that i`m strugling in , the case study is in donna C.S. summers text book ( quality text book)
its about a simplified version of a bracket used to hold a strut in place on an automobile. welded to the auto body frame, the bracket cups the strut and secure it to the frame with a single bolt and a lock washer. proper alignment is necessary for both smooth instullation during assembly and future performance. for mounting purposes the left side hole must be alligned on center with the right side hole and the angle between hole centers will equal to zero , the bracket is created by passing coils of flat steel through a series of progressive dies. as the steel moves through the press , the bracket is stamped, and finally bent into appropriate shape , recently the customers have been complaining about having difficulty securing the brakcet closed with the bolt and lock washer . the bolts have been difficult to slide through the holes and then tighten. Assemblers complain of stripped bolts ans snug fittings. the problem -solving cycle begins with "Recognizing the problem and estabshlishing pritorities." Bracket customers have made management at WP Inc.((the company)) well aware of the problem.Because management is unsure of the root cause of the problem , they proceed with the second step of problem solving and assemble a team
. the team consists of representatives from process engineering, materials engineering , product design and manufacturing. beginning with defining the problem , the team has decided to brain storm the reasons why this problem has occured
the team decided to develop performace measures to answer ,the problem is Difficulty securing brakets closed wuth bolt and locknut !!! ANd the assignment is about creating a cause and effect diagram and brain storm potential root causes for the problem . actually i know how to do the diagram but i have No idea what are the causes of the problems ! have u got any idea !!
and the other assignment is about doing another cause And effect diagram Ans the problem in the 2nd part Is that the most likely cause of the problem is experienced by customer is alignment of the holes at some stage of the formation process where the holes end up off center So here we i should do another cause and effect diagram about the root causes of improper hole alignment So have u got any idea about the causes please help me !!
In brief ,
its about doing 2 Cause and effect diagram ((fish Bone diagram)) and brainstorm potential root causes for these problems:
1- difficulty securing brackets closed with bolts and locknut
2- improper hole allignment ((knowing that after doing the first cause and effect diagram , engineering determine that the most likely cause of the problem experienced by the customers is the allignment of the holes
