B-splines

Software; CAM

A b-spline is a mathematical function that defines free-form curves and surfaces. IGES files that use b-splines instead of parametric splines are generally smaller in size.

A bubble is a spherical, internal void caused by air or other gas trapped within a moulded plastic product. A bubble differs from a blister in that the bubble is contained within the part, whereas a ...

Burn mark

Software; CAM

A burn mark is a defect that appears as a brown or black mark on the part surface. A burn mark can be caused by an un-vented air trap. This occurs when the trapped air is heated very quickly as it is ...

Air trap

Software; CAM

An air trap is an air or gas bubble that has been trapped by converging flow fronts or trapped against the cavity wall. This causes a surface blemish on the part. Air traps can be prevented by ...

Amorphous polymers

Software; CAM

Amorphous polymers are a family of polymers that are characterised by entangled polymer chains that are loosely bound. The term amorphous indicates that there is no preferred orientation of the ...

Aspect ratio

Software; CAM

Aspect ratio normally refers to the relation between width and height of a mesh element. These are important because they affect analysis accuracy. Aspect ratios are especially important in sensitive ...

Batch

Software; CAM

A batch is the quantity of polymer that is made in one operation. A batch is also referred to as a lot In CAE products, batch refers to the execution of consecutive analyses in one operation.
