7 7  There can be several working coordinate systems and they can be switched with codes [[(% style="color:#a0be2d" %)//**G54-G59**//>>doc:Руководство пользователя.Описание G-кодов.Список G-кодов, поддерживаемых системой.G40-G79.G54-G59\.3: Выбор системы координат]](%%). The offset of each of them relative to machine zero is stored in non-volatile memory and the next time it starts, it will be __automatically restored after the homing operation__ (see [[Why do I need to do a homing?>>doc:Руководство пользователя.Ответы на типовые вопросы.Для чего нужно делать поиск базы?.WebHome]]). If the search for the home is not done, then the working zero offset will still be restored, but so far the current machine coordinate is conditionally unknown, then the working one is also incorrect. Thus, the main advantage of the operation “homing” is the accurate restoration of the working coordinates of the machine after turning off the power, which allows you to easily continue long-term processing in the next work shift.

11 11  Consider, for example, a milling machine, on the work table of which there is a vise, a rotary axis and directly in the table there are several mounting holes, the machine coordinates of which are known. In this case, it is convenient to place the zero of one of the coordinate systems in the center of rotation of the rotary axis, the second somewhere in the center of the vise field, and the third in one of the mounting holes. In this case, after each search for the base, these coordinate systems will restore their position. Now, when preparing the G-Code in the CAM system, you just need to specify where the working zero will be located, depending on which of the methods of fastening the workpiece, the G-Code is made.
