10.3.9 Predrilling contour pocket (CYCLE64)
Function
In addition to predrilling, the cycle can be used for centering. The centering or predrilling
program generated by the cycle is called for this purpose.
The number and positions of the required predrilled holes depends on the specific conditions,
e.g. type of contour, tool, plane infeed, finishing allowances.
If you mill several pockets and want to avoid unnecessary tool changes, predrill all the pockets
first and then remove the stock. In this case, for centering/predrilling, you also have to enter
the parameters that appear when you press the "All parameters" softkey. These parameters
must correspond to the parameters from the previous stock removal step.
Programming
When programming, proceed as follows:
1. Contour pocket 1
2. Centering
3. Contour pocket 2
4. Centering
5. Contour pocket 1
6. Predrilling
7. Contour pocket 2
8. Predrilling
9. Contour pocket 1
10.Stock removal
11.Contour pocket 2
12.Stock removal
If you are doing all the machining for the pocket at once, i.e. centering, rough-drilling and
removing stock directly in sequence, and do not set the additional parameters for centering/
rough-drilling, the cycle will take these parameter values from the stock removal (roughing)
machining step. When programming in G code, these values must be specifically re-entered.
Note
Execution from external media
If you execute programs from an external drive (e.g. local drive or network drive) then you
require the execution from external storage function (EES).
