Pain points of traditional solutions on the market:
Current traditional machining methods generally rely on manual programming or point teaching based on hole parameters marked on CAD drawings. This requires a significant amount of time to verify the coordinates of machining points, resulting in a decline in both machining efficiency and productivity, and also suffers from a lack of ease of operation. The process of converting CAD drawings to NC files is also very cumbersome, still requiring third-party software to complete the format conversion.
Advantages of Positive Motion Technology Solutions:
Against this backdrop, the Zheng Motion Technology CNC System CAD Drilling and Tapping Center Solution is developed based on the VPLC532E machine vision motion control all-in-one machine. It supports the direct import of DXF format files generated by CAD. By selecting graphic layers or hole features, the corresponding NC file can be generated with one click, eliminating traditional cumbersome operation steps and significantly improving the ease of operation.

Design of positive motion technology solutions
1. 24DI: Connects to the tool setter, air pressure sensor, and switch signals, etc.
2. 12DO: Connects to the oil pump, electric spindle, etc.;
3. USB 3.0/USB 2.0: USB port for connecting the touchscreen;
4. EtherCAT: Connects to the bus servo drive and servo spindle;
5. CAN: Connects to the handwheel extension board.
CAD to NC conversion with one click
When importing CAD software to generate DXF files, the graphic information is loaded into the Table register. The system parses the corresponding information based on the selected layer and displays the center coordinates and radius parameters of that layer on the interface. After selecting the tapping/drilling mode, the NC file is automatically generated based on the hole position information. Machining parameters, including hole depth, number of repetitions, hole bottom dwell time, and rotation speed, can be configured through the process settings interface. After confirmation, the NC file is generated with a single click.
The system automatically plans the processing path based on the center coordinates of the circle by default, and also provides a shortest path optimization option to achieve intelligent path arrangement.

For DXF graphics that deviate from the origin, the automatic offset function can be enabled. The system will automatically compensate for the offset of the graphics to ensure that the NC file and the machining position are accurately matched, avoiding machining errors caused by coordinate system deviation.
When multiple processing operations are required on the same graphic, the array function can be used. After selecting the target hole position, enter the number of rows and columns and the corresponding spacing parameters in the array settings interface. After confirmation, the system will automatically generate the array arrangement.
