tangent the vertical cutting tool before reaching the second path

[mmm20ymmm]

I am writing regarding a question about a vertical cutting tool which is used to cut glass shields and the G-Code required for specific task. We have a cutting tool in order to cut glass shields into pieces and we want it to follow a path. It cuts a line and then elevates and move to another point and follow the new path. What command I can use to make the tool tangent to the new path when the tool is in the air and is moving toward the starting point of the second path.

Does your machine have a separate axis that rotates the tool? In that case you can probably can control it like a regular rotating axis, such as "G0 C180.0".

Yes, but in the settings of our CNC the third axis is defined as the tangent of the path and the defined G-Code is a function of x and y only. Now it works fine but it tangent the tool on the glass shield. We aim to do so while the tool is elevated from the sample and is moving towards the target point.

Except this method you mentioned, could we the same x, y and tangent to achieve this aim or we need to define a third axis.

So the controller automatically orients the C axis based on the X/Y movements? What happens if you raise the tool and make a lead-in move before lowering the tool again?

hy use interpolated rapid + radius compensation, or feed it directly at required position
