Tangential Cutting

MyCNC CNC control software supports tangential cutting control, providing an all-in-one solution for any cutting needs. No special CAM programming is needed to generate the necessary rotation/lift G-code commands - the myCNC software generates the tool path automatically upon importing the DXF/HPGL file.

The myCNC application supports a number of tangential cutting features, including

DXF/HPGL import
Quick tool assignment based on layers in the original DXF file
All-in-one solution for complex systems - able to run a job with both tools that require tangential cutting control (knives, half-knives, creasing wheels), and tools that do not (spindle, camera) while only loading in a single DXF file.
Distortion and shift correction via marker recognition using the CNC Vision system (offered separately)

Tangential cutting is thus typically done via the following steps:

A video with a quick recap of technology assignment and DXF import for tangential cutting is available:

Standard 2 axis G-code files (X and Y motion) are suitable for tangential knife cutting. It's possible to use 2D DXF files for tangential knife cutting as well. In case several cutting heads are used (tangential knife, creasing wheel, half height knife, 45 degree knife, spindle, marker, laser pointer etc) each tool should be drawn in its own separate layer. DXF import allow to assign a tool for every layer and to set up the lift height, cutting height, feed rate and other parameters for every tool.

Once tangential cutting control is activated, myCNC CNC control software will automatically generate the output G-code file, inserting all the necessary tool change and tool raise/lower macros.

The following videos show the myCNC controller system being used on tangential cutting machines:
