A cost reduction case achieved by transforming excess quality products into optimally shaped quality products.

We will expose excessive quality and carry out improvements (optimization tolerances). By representing quality optimization in drawings and shapes, we can derive cost reductions.

■Introduction of methods for quality optimization based on specifications, enabling cost reduction through a review of optimal shapes. ■Improving quality, delivery time, and price is also important to tackle through case studies! The first step begins from this site. ■What is necessary when setting tolerances to reduce defect rates? There are various methods to mitigate defect rates. This image is one of them. However, it is important to note that this method may lead to increased costs. Key Point: Setting tolerances optimized for processing is crucial. ■Original design pursuing ease of integration, improvement measures focusing on processability. Original type: The bearing is supported at the shoulder part that narrows from the center of the shaft. ■Improved type: The shaft is made straight, and the bearing is supported at the holder side. Key Point: It is important to choose shapes with low processing costs. ■As an issue: As a result of clarifying the causes of frequent defects, advice was given that establishing a step on the shaft for assembly would reduce defects more than determining the tolerances for the bearing support part from the holder side of the processor, leading to this shape.
