The additional module Cenon CCD optically measures printed workpieces. Thus a common annoyance will become obsolete in future – a workpiece has been elaborately printed and then the contours will not be hit exactly when the workpiece is milled later on. In the worst case, the whole plate has to be discarded then. Reasons for this are inaccuracies of the printing process and while manually adjusting the workpiece on the CNC milling machine.
Cenon CCD offers a remedy here by capturing with the camera register marks which are printed on the workpiece itself. A new shape of the register marks can be easily taught to the software.
Scaling in all directions
The software independently adjusts the machining paths for the output according to the captured positions of the register marks with the help of a flexible transformation grid. That means they will be aligned by rotating, proportionally scaled or they will be stretched respectively compressed in one direction. So all kinds of inaccuracies of the printing process can be compensated. The result will be an accurately machined outline which is exactly next to the printed contour.
This method is suitable for milling, engraving and drilling as well as for cutting with a tangential knife. Furthermore, it can be used for quite different kinds of applications: for instance an industrial manufacturer may want to process silk-screen printed front plates or plastic foil keyboards.
Optical measurement of printed workpieces with Cenon CCD
And due to the more and more powerful and inexpensive large-format printers, the field of sign making constantly offers new possibilities and applications under the keyword print & cut. It is also possible to recognize the edges of the material if you want to identify the position of your workpiece on the machine table.
Another useful field of application is processing oversized workpieces: If they don’t fit completely on the machine table, they can be moved in several steps under the bridge and then they will be machined stage by stage. And finally, you can use drill holes as marks for precisely reversing your workpiece for a double-sided machining.
- optical recognition of register marks on the workpiece with a CCD camera system
- import of i-cut data with register marks and outline path
- comparison of the captured actual values with the saved reference values
- automatic positioning and alignment or scaling (including stretching/compressing in one direction) of the output graphics by the software
- alternatively operation in positioning and scaling mode or only in positioning mode (if the final product shall have an exactly defined size)
- capturing of workpiece corners so that the position and alignment of your workpieces on the machine table can be identified contact-free
- drill holes can be used as marks for precisely reversing your workpiece for a double-sided machining
- machining of oversized workpieces by stages possible
- camera preview where the capturing process of the marks can be followed
