Difficult Approach Conditions in NX CAM

NX CAM QuickTip | How to master difficult approaches on the turning machine

Heinrich Flaum | 02/28/2023

In this NX CAM QuickTip, we will deal with challenging turning operations and how you can master them thanks to Siemens NX. Do you have a turning operation that seems impossible because of inaccessible or difficult geometries and thus difficult approach conditions? We'll show you how to solve this in Siemens NX.

To do this, we made up a tricky part and a tricky manufacturing operation today. Our part has a hollow geometry that we want to turn out on the inside.

In our operation settings, we take a closer look at the manufacturing area and see: our tool can't get into the hollow geometry, because it crashes with the bottom of the part.

The tool collides with the lower part of our part.

In this video we show you step by step how to approach to difficult geometries thanks to Siemens NX.

With the settings in the approach path when turning, you can not only specify points for the toolpath, but also have the tool axis interpolate from one point to the next. Through these settings we can define the Approach and Retract of our tool as required by our part. In the machine simulation, we can see that our tool now threads into the part as programmed and then starts turning (right picture).
