The outward force exerted on the mold halves caused by the injection of molten material during the mold filling stage. The separating force is the product of the cavity pressure and the projected area of the shot. The clamp force applied to the mold must be greater than this separating force in ...
In order to machine a feature that is wider than the width of a single cut, the tool must make several cuts, stepping to the side after each one. This step-over distance is equal to the radial depth of cut for each cut and must be less than or equal to the tool diameter. The size of the step-over ...
The average time required to pack a single part into a box. The average pack time should be based on the total time to pack the box, including the time to load the parts, add filler if needed, and seal the box. The pack time can reflect the time to manually pack the part or the time required from a ...
Those properties of a material that reveal the elastic and inelastic reaction when force is applied, or that involve the relationship between stress and strain; for example, the modulus of elasticity, tensile strength, and fatigue limit. These properties have often been designated as "physical ...
In many processes, scrap material is generated from mold feed systems or defective parts and can be recycled by mixing it with unused material. The recycle ratio is the amount of scrap allowed to be recycled relative to virgin material. The scrap allowed to be recycled by this ratio is often less ...
The order quantity or yield quantity is the number of parts required from a manufacturing process to fill a buyer’s total or annual order or to be used in a subsequent process. Due to the defect rates that are inherent to many manufacturing processes, a larger production quantity or run quantity ...
The amount of force required to deep draw a sheet metal blank to a smaller diameter determined by the punch. The required force will depend upon the material, sheet thickness, and drawing ratio. The drawing force will create enough stress in the material to exceed the tensile yield strength, ...
The length that the cutting tool travels at a specified feed rate in order to perform an operation. The cut length can be calculated based on the operation type, feature dimensions, and cutting parameters. The cut length includes the distance to engage and exit the workpiece, but does not include ...
