The document offers practical cost-saving guidance for customers purchasing precision turned and machined components, emphasizing proactive planning, clear specifications, and early communication to minimize tooling, setup, and material costs while ensuring functional requirements and quality. Key Points Quantity planning: Share annual requirements and update prints on re-orders to reduce tooling, setup, and material costs through longer contracts and manufacturing flexibility. Over/under runs: Build in anticipated overage in quotes since exact quantities raise costs; allowances depend on production factors like bar length and equipment. Delivery forecasting: Provide accurate forecasts and allow lead time to enable economical production versus premium fast-delivery costs. Packaging considerations: Inform about special packaging, labeling, or bar coding early to explore cheaper alternatives if possible. Material selection: Prefer standard free machining grades and sizes to lower costs and improve production efficiency and tolerances. Tolerances: Use only as-close-as-necessary tolerances; tighter tolerances raise costs and may require more expensive processes. Dimensional relationships: Avoid specifying strict dimensional relationships unless required to prevent expensive fixturing and slower production. Concentricity guidance: Specify concentricity limits at maximum allowable values to avoid manufacturing and inspection difficulties. Internal diameters: Specify hole sizes to maximum allowable limits; standard tooling is available, while special diameters require extra tooling. Sharp corners: Prefer chamfers or radii unless a sharp corner is functionally required to avoid damage and extra handling. Threads: Use standard ANSI threads with appropriate fits; special threads demand special tools and may need additional operations. Burr management: Do not mandate burr removal unless essential for function due to added processing. Finish requirements: State only the necessary surface finish to meet function; finer finishes can incur slower processes and handling. Quality requirements: Be explicit about critical quality characteristics, data needs, and inspection routines to align production with expectations. Gages and equipment: Favor designs that avoid special gages; if needed, customers can provide them to reduce costs. Plating and heat treating: Specify plating thickness and post-plating tolerances clearly; provide complete heat-treat details (depth, core hardness, temperatures) and reference recognized standards where possible.
