    A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...

    Management costs exists because reusable plastic container stock count needs to be managed. The final cost of reusable plastic containers is the cost incurred when packages are lost or there are errors within the management system. [6] Figure 2 provides a detailed summary of the costs associated with adopting reusable plastic containers.

    en.wikipedia.org/wiki/Basis_of_estimate

    Basis of estimate (BOE) is a tool used in the field of project management by which members of the project team, usually estimators, project managers, or cost analysts, calculate the total cost of the project.

  6. Castability - Wikipedia

    en.wikipedia.org/wiki/Castability

    A very castable part design is easily developed, incurs minimal tooling costs, requires minimal energy, and has few rejections. [2] Castability can refer to a part design or a material property . [ 1 ]

  7. Permanent mold casting - Wikipedia

    en.wikipedia.org/wiki/Permanent_mold_casting

    The high tooling costs make this process uneconomical for small production runs. When the process is used to cast steel or iron the mold life is extremely short. For lower melting point metals the mold life is longer but thermal fatigue and erosion usually limit the life to 10,000 to 120,000 cycles.

  8. Tipped tool - Wikipedia

    en.wikipedia.org/wiki/Tipped_tool

    A tipped tool is any cutting tool in which the cutting edge consists of a separate piece of material that is brazed, welded, or clamped onto a body made of another material. In the types in which the cutter portion is an indexable part clamped by a screw, the cutters are called inserts (because they are inserted into the tool body).
