Processing Apparatus

A processing apparatus for a workpiece, comprising:

• a central control unit;
• a processing quality prediction unit;
• a processing unit;
• and
• a tool compensation unit, wherein said processing quality prediction unit, said processing unit and said tool compensation unit are respectively connected with said central control unit electrically, wherein said processing quality prediction unit implements a virtual processing quality prediction method to establish a quality prediction model to predict a processing quality of the workpiece, output an accurate data of quality to said central control unit, and generate at least a tool path for said processing unit to process the workpiece, wherein said central control unit judges data from said processing quality prediction unit and outputs said data to said tool compensation unit to calculate tool compensation data, wherein said tool compensation unit provides said tool compensation data to said processing quality prediction unit to form a new processing path, wherein said processing unit implements a compensated processing path to process the workpiece.
