CAM
Viscosity index
Software; CAM
The viscosity of the material at 1000 1/s shear rate and at a specified temperature. For example, VI(240)125 means that the material has a viscosity of 125 Pa.s at a shear rate of 1000 1/s and a ...
Zero screw position
Software; CAM
The zero screw position is the furthest forward position possible for the screw. This is when the end of the screw is in contact with the barrel or hits machine 'stops'.
Thermal degradation
Software; CAM
Thermal degradation is a break down of material quality, resulting in poor parts. Thermal degradation may occur if the barrel temperatures are too high, the rotational speed of the screw is too fast, ...
Free-form curves and surfaces
Software; CAM
These curves and the surfaces that are formed from them follow no mathematical relationship.
Family name
Software; CAM
This is the name of a family of materials, for example, Polycarbonate. Each material is a member of a family of materials. The shortened version of a family name is the family abbreviation. For ...
Velocity to pressure change-over
Software; CAM
This is the position of the screw when the machine switches the screw displacement control from velocity control (used in the filling stage), to pressure control (used in the packing stage.)
Family abbreviation
Software; CAM
This is the shortened version of a material family name. For example, PC is the family abbreviation for the family name Polycarbonate. Some families contain subsets, and there is an abbreviation for ...
