# Block search and profiled tube machining

## Resuming path approach

Please note the following when path motion is resumed on profiled tubes with the block search function:

- The approach motion in an area with an active #CYL [EDGES..] or #CYL ORI PROFILE [EDGES=…] takes place on the ACS plane. To prevent any collision between tool and workpiece, position the tool at a sufficient safety height (U axis rotates without compensation motion of Z).
- The tool must be perpendicular to the profile surface and within the capture range of the profile (see figure below).
- The approach motion is executed in two steps:

1. Approach motions without Z axis (e.g. U, Y, X)
2. Approach motion of the Z axis
