Dental machining system for predicting the machining time for manufacturing a dental restoration/appliance

A dental machining system for manufacturing a dental restoration/appliance, comprising:

• a dental tool machine comprising:
• a dental blank holder for movably holding at least one dental blank relative to one or more dental tools,
• one or more driving units each for movably holding one or more dental tools;
• and
• a control unit for controlling the dental blank holder and the driving units based on construction data of the dental restoration/appliance and a plurality of machining processes specific for the manufacturing of the dental restoration/appliance from the dental blank;
• wherein the control unit is further adapted to execute a trained artificial intelligence algorithm adapted to predict a machining time for manufacturing the dental restoration/appliance based on input data comprising:
• process parameters defining the machining processes respectively;
• and
• mappings which include information on a target geometry of the dental restoration/appliance, which are constructed based on said machining processes,
• wherein the mappings comprise:
• first type of mappings that describe the target geometry of the dental restoration/appliance relative to machining directions (z) in the respective machining processes, wherein the machining directions (z) are parallel to the one or more dental tools,
• wherein the first type of mappings further describe a distance from a surface of the target geometry of the dental restoration/appliance to a reference plane of the one or more driving units or the distance from the surface of the dental blank to the surface of the target geometry of the dental restoration/appliance.
