OK, thanks, your answer helped me.
In fact I had only selected the lathe preset. With this preset, it is impossible to have the views perfectly oriented. On the other hand, by selecting the normal preset, and by assigning a rotation of 180° around X and 90° around Y, the display is perfect.
For the display of the X up, my turret is in the up position. So my X+ upwards like the physical machine.
For cycles, like roughing cycles, it's not a priority as you say. I would prefer to work on the tool table with the management of radius compensation G41/G42 when you have time.
