Terminology

OP

Operation in the manufacturing process, such as a clamp closing or a robot moving from one position to another. An OP is an object contained within a group. OPs have a common starting signal which is the Group START, but have individual signals used to denote the end or stop of the OPs motion.

Cycle

A Cycle is a sequence of events that repeat continuously. In the case of a Group or OP, it is the duration of one individual motion sequence, such as a clamp closing or a robot moving from one position to another. An Asset's Cycle is the summation of all the individual Group cycles that are used to show what is considered to be a major Motion event. This can be in the form of the process required to perform all the work required on a part in one station, a robot's programmed path from a common position back to that same position (commonly its home position), or in the case of a Summary Asset it is the series of Motions, such as a fixture clamping sequence, that have been shown in more detail in a separate Asset.

Baseline

Baselines are used to signify the expected or designed duration each Motion will experience.

Tolerance

Tolerances are used to denote the amount of variation from the baselines there can be before the Motion is flagged.

Models

Models are used to signify a major Motion path that needs independent Baselines assigned to these Motions. ePVS uses the Model tag as a pointer to the appropriate Baseline Cycle Time values entered for each group of the Asset. 

Options

Options are used to signify part type differences where the major Motion remains the same and existing Baselines and Tolerances can be used.

Summary Asset

A Summary Asset can be used in situations where there is a high density Overall Station Asset or when there is a tool change that can have considerable sequences changes. This Asset is generally used to combine large tooling fixtures into smaller Summary Groups in the Overall Station Asset, but maintains the level of detail desired in a separate sub-asset. Some examples could include changeable framing gates, fixtures mounted on tool-trays, or even high unit count fixtures mounted on pallet transfer systems.
