SINUMERIK 840D sl Commissioning Manual CNC: ShopMill – 11/2006 Edition
You can link user cycles into the machining plan with the ShopMill "Positions"
cycles.
The name of the cycles to be linked in the work plan is mandatory and must not
be changed:
E_DR_Ox
with x = 1 to 8
The following variables must be configured within the cycles:
You must first define three variables which are not assigned until the program
step is inserted in the machining plan, i.e. the attribute must be assigned invisi-
bly (wr0) to the input field of each variable. The variable sequence is as follows:
1. Variable for the next tool, data type String (S)
2. Variable for the position identifier in objects, data type Integer
3. Variable for the sequencer text that is to be displayed in the ShopMill work
schedule, data type character string (S)
The easiest way to assign a value to this variable is in a LOAD method.
Two variables for cycles processing must also be defined as well as one vari-
able for each toggle field which has a different display content on the interface
(e.g. mm/rev) than the internally transferred quantity (e.g. 1).
You need to assign the attribute invisible (wr0) to these variables too as they do
not have their own input field. You can place the variables in any order.
Note
When an OUTPUT method is used, all variables described above must be
configured within this method so that they can all be interpreted on
recompilation.
If an operating step should not be performed at all positions but, instead, only
once, the user variable E_ONETIME = 1 must be set in the corresponding
cycle. This allows for implementing modal changes for the subsequent technol-
ogies.
Application example:
Toggle between the parallel axes W and Z for a boring mill.
