A digital marking processing apparatus includes a central control unit, and a processing quality prediction unit, a processing unit and a marking unit which are respectively connected with the central control unit electrically. The processing quality prediction unit can implement a virtual processing quality prediction method to predict the processing quality of the workpiece, output an accurate data of quality to the central control unit and generate tool path for the processing unit to process the workpiece. The central control unit is able to compile the data of quality from the processing quality in prediction unit into file information, so that the marking unit can then utilize the file information to correspondingly mark barcode or other digital pattern on the workpiece, which facilitate workpiece management and information disclosure.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A digital marking processing apparatus for a workpiece, comprising: a central control unit; a processing quality prediction unit; a processing unit; and a marking unit, wherein said processing quality prediction, said processing unit and said marking unit are respectively connected with said central control unit electrically, wherein said processing quality prediction unit implements a virtual processing quality prediction method to predict a processing quality of the workpiece, output an accurate data of quality to said central control unit and generate a tool path for said processing unit to process the workpiece, wherein said central control unit is able to compile the data of quality from said processing quality prediction unit into a file information, so that said marking unit is able to then utilize said file information to correspondingly mark barcode or other digital pattern on the workpiece. 2. The digital marking processing apparatus, as recited in claim 1, further comprising a workpiece transporting unit connected with said central control unit electrically, wherein said workpiece transporting unit transports the workpiece to said processing unit for processing and sends an information of workpiece transportation to said central control unit. 3. The digital marking processing apparatus, as recited in claim 2, wherein said workpiece transporting unit is a robot arm. 4. The digital marking processing apparatus, as recited in claim 1, wherein said marking unit is a laser marker. 5. The digital marking processing apparatus, as recited in claim 1, wherein said marking unit is a pneumatic marker.
