The Contact page includes the definitions for thermal contact parameters and thermal friction. The user may define different contact conditions between different tools and blank, as illustrated in Figure 8.3.116.

THERMAL CONDUCTIVITY: thermal conductivity between gaps.

RADIATION FACTOR

HEAT TRANSFER COEF.

MIN. GAP: If the gap is less than this value, use htc value.

MAX. GAP: If the gap is greater than this value, there is no thermal contact.

ALGORITHM: thermal contact algorithm.

THERMAL BOUNDARY CONDITIONS ARE OFF WHEN PARTS ARE IN CONTACT.

THERMAL FRICTION REQUIRED: Defines the curve between dynamic/static friction coefficient and temperature.
