E4
Defines the label number of the block where the geometrical description of the profile of the part
ends.
Q6
Defines the number of the program that contains the geometrical description of the profile.
This parameter is optional and if it is not defined, the CNC assumes that the profile is defined in
the same program that is calling the cycle.
Considerations
The machining conditions (feedrate, spindle speed, etc.) must be programmed before calling the
cycle.
The canned cycle calling point must be off the part to be machined and at a distance greater than
the one defined as excess stock (I) of the most external profile of the part.
If the tool position is not correct to execute the cycle, the CNC will display the corresponding error.
Once the canned cycle has ended, the active feedrate will be the last one programmed, i.e. the one
corresponding to the roughing operation (F) or to the finishing operation (H). The CNC will assume
functions G00, G40 and G90.
Optimizing the machining operation.
If only the desired profile is defined, the CNC assumes that the original stock is cylindrical and
machines it as shown on the left.
When the stock profile is known, it is recommended to define both profiles: The profile of the original
stock and the desired final profile. The machining operation is much faster because only the stock
delimited by both profiles is removed.
