Machines Methods Materials Our company has a part that is constantly coming out with a diameter out of specification and is creating a lot of rework. We have had discussions in the past with our supplier about the steel hardness out of tolerance they provide, making it difficult to manipulate the parts in the process. One of our inspectors has been reporting that the calipers are hard to read when doing his inspection of this diameter. The maintenance department has been asking for downtime in production to do maintenance since the coolant needs change on CNC used to cut the part. There is a new employee working this part, he has been with us for 6 months; he is also complaining about the low lighting in the production area and we discovered the wrong size tool being used to cut the part. Use the categories in the diagram attached to classify the causes per the problem description. List one possible cause per one fishbone category for the diameter out of specification problem in the following format example: Materials - Paper thickness, People - sick employee Find one cause per category, all 6 are required Machines Methods Materials Our company has a part that is constantly coming out with a diameter out of specification and is creating a lot of rework.
