Turning cycle
3.4.3 Basic operation (levels 1 and 2)
The machining steps in this cycle are as follows:
1. If the roughing operation was programmed with another tool the CNC makes a tool change,
moving to the change point if the machine so requires.
2. The spindle starts with the speed selected and in the direction stated.
3. The tool approaches the starting point (Xi, Zi) in rapid, keeping the selected safety distance
according to axes X and Z.
4. Roughing operation, with successive turning passes, up to a distance from the selected final
diameter equal to the finishing stock.
This operation is carried out with the conditions set for the roughing operations; however, the
CNC calculates the actual (real) pass so all the turning passes are identical. This pass will be
equal to or under the defined value
.
Each turning pass is done as shown in the figure, starting at point "1" and after going through
points "2", "3" and "4", ending at point "5".
5. Finishing operation.
If the finishing operation has been programmed with another tool, the CNC will change the tool
and will move to the change position if so required by the machine.
The finishing of the part is carried out with the machining conditions set for finishing; feedrate
of the axes (F), spindle speed (S) and turning direction.
6. Once the operation or cycle has ended, the tool will return to the position it occupied when calling
the cycle; i.e. to the point where [START] was pressed.
When executing an entire part, combination of operations or cycles, the tool does not return to
that point after executing each cycle.
7. The CNC stops the spindle, but it keeps the machining conditions set for finishing; tool (T),
feedrate of the axes (F) and spindle speed (S).
