Metal Forming - 7.3 FormingPositionsType ObjectType Definition

The FormingPositionsType (see Figure 12) defines characteristic positions of a forming process and is formally defined in Table 16. For each cycle, the selected positions will get the ActualValue, Setpoint, EURange, EngineeringUnits and corresponding CycleCount as a CyclicProcessValueType, defined in 7.2. Figure 13 shows a hydraulic press machine with a cushion, indicating the positions of the characteristic points of a forming process.

MetalForming FormingPositionsType

TDC is defined in the Metal Forming terms 3.2.1.

Start defines the starting point of a forming process, which can be different to TDC.

Touch defines the position where the workpiece and tool have their first contact.

BDC is defined in the Metal Forming terms 3.2.1.

Retract defines the position where workpiece and tool separate from each other.
