TPM Instructor Course. The largest source of Setup and Adjustment time is typically changeovers (also referred to as make ready or setup), which can be addressed through a SMED (Single-Minute Exchange of Dies) program. Yield loss on wafers results in microchip failure at the specified region on the wafer which impacts the customers due to poor product reliability. Process Defects account for defective parts produced during stable (steady-state) production. Zero-loss mentality, as part of the foundational element of TPM, does not consider yield loss to be acceptable. TPM also aims to improve the efficiency and effectiveness of manufacturing companies as a whole. Office TPM addresses nine major losses which are processing loss, cost loss including in areas such as procurement, accounts, marketing, sales leading to high inventories, communication loss, idle loss, set-up loss, accuracy loss, office equipment breakdown, communication channel breakdown, telephone and fax lines and time spent on retrieval of information. From the broader perspective of unplanned stops, other common reasons include no operators or materials, being starved by upstream equipment or being blocked by downstream equipment. A more generalized way to think of Setups & Adjustments is as any planned stop. The term “Total Productive Maintenance” was first used in the late 1960’s by Nipponese, a supplier of electrical parts to Toyota. Examples of common reasons for Reduced Yield include suboptimal changeovers, incorrect settings when a new part is run, equipment that needs warmup cycles, or equipment that inherently creates waste after startup (e.g., a web press). 1445 Industrial Dr., Itasca IL, 60143 USA, © 2002-2019 Vorne Industries Inc.
