Vocabulary Term Definition
batches A specific number of the same part that moves throughout a production cycle.
cell A U-shaped arrangement of various machines structured around the design of similar products. Cells encourage smooth product flows and use space efficiently.
CNC machine A machine tool that uses programs to automatically execute a series of machining operations. CNC machines offer increased productivity and flexibility.
continuous improvement The belief that an organization must constantly measure the effectiveness of its processes and strive to meet more difficult objectives to satisfy customers.
error detection The inspection of a part before it has been completed to determine if it conforms to specifications.
error device Any tool or process used to reduce or eliminate errors from a manufacturing process.
Five S Approach A targeted list of activities that promotes organization and efficiency within a workspace. The Five S terms are sifting, sorting, sweeping, standardizing, and sustaining.
fixture A special workholding device used to locate and clamp a part onto a machine tool.
inspection The examination of a part to determine if it conforms to specifications. Inspection traditionally follows the completion of a part.
inventory The storage of raw material, in-process parts, and completed, manufactured products. Excess inventory is considered waste.
kanban A small card or visual tool that signals the movement of parts within a pull system.
lead time The time spent between the original customer order for a particular product and its final delivery to the customer.
lean manufacturing An approach to manufacturing that seeks to reduce the cycle time of processes, increase flexibility, and improve quality. Lean approaches help to eliminate waste in all its forms.
optical comparator A sophisticated measuring instrument that projects an image of a part onto a screen to compare the shape, size, and location of its features.
processes A set of activities that uses resources to transform inputs into outputs. Essentially, a process describes the way "things get done."
product changeover The time it takes to tear down the setup for the current product type, prepare for next product type, and successfully produce the first good part.
product flow The movement of products within the shop during each stage of the part's manufacturing process.
pull system A production system characterized by smaller batches, quick responses to customer demand, and smooth product flow.
waste Any thing or process that does not add value to a product. The goal of lean manufacturing is to eliminate waste.
