The adaptive processing system scans the workpiece characteristics by gripping the scan head with the robot and then through the linkage of the robotic arm and the fixed workpiece turntable. The scan results can generate a physical model, which can be compared with the theoretical three-dimensional numerical model of the workpiece in order to automatically optimize the physical model and the theoretical model, or manually adjust the coordinate values, quickly analyze the surplus distribution of the workpiece, and meet the workpiece dimension detection requirements. Dimensionally qualified workpieces are placed and fixed on a 5-axis processing device by means of a manually operated transfer trolley, and the scan results are transmitted to a 5-axis processing device through a local area network. The processing device can automatically process the reference hole and reference plane of the workpiece based on the scanning result.

1) The schematic for teh scheme layout is as follows:

2) Overview of the overall workflow:

Automatic optical scanner scans the data, outputs the STL file, and then imports it to auxiliary detection processing software module

               

After alignment, the software adjusts the appropriate processing allowance and generates the program

                          

The transfer trolley transfers the workpiece to the processing center

                          

The machine tool completes the processing of the workpiece according to the generated program.

3) Description of overall workflow

(1) The workers place the workpiece on the scan system and scans the non-processed side for the first time (added with a measuring platform to facilitate the personnel to prepare the next workpiece outside the measurement system). The reference point is attached to the tooling and the workpiece itself is affixed with 4-6 points.

(2) CAD import software automatically generates the measurement program.

(3) The measurement is started. After the measurement is completed, the workpiece is flipped.

(4) The reverse processing program is automatically generated and the measurement is started.

(5) After the measurement is completed, the front and back surfaces are combined and patched. The software outputs the grid data of the STL workpiece.

(6) CAD data input auxiliary detection processing software module enters the calculated STL data.

(7) The software aligns with the STL through the best fitting and manually adjusts the appropriate allowances for the various processing surfaces.

(8) The transfer trolley transfers the platform and the workpiece together to the CNC.

(9) Renishaw probes detect the position of the tooling or workpiece. The measurement point import auxiliary detection processing software module performs secondary alignment and aligns with the grid STL and CAD.

     (10) According to the offset, the software automatically generates an offset program for processing.
