CHAPTER 1 SCREEN OPERATIONS

Returning to the restart position

1) Do not carry out the following operations. Doing so prevents correct returning to the
machining restart position.
Changing the conditions such as tool offset amount or parameters after restart search is
executed.
→ Set the various conditions such as tool offset amount and parameters before
executing restart search.
Carrying out automatic operation or MDI operation before starting the program that is
restart searched.
Using user macro external signal input, machine coordinate read or external mirror
image, etc., in the restart searched program.
Carrying out operations such as manual or MDI interrupt to shift the coordinate systems
when executing the previous machining program.
NURBS interpolation mode
1) A block in the NURBS interpolation mode cannot be designated as a restart position.
A search error will occur.
2) If a block immediately after the NURBS interpolation mode is designated as the restart
position, the restart search will be completed. However, when restarting, the modal in the
blocks in the NURBS interpolation mode is used so an illegal operation will take place. At
this time, the "Research after NURBS invalid" error will occur when starting, and starting
will be inhibited.
Restart search
1) A macro statement block cannot be searched.
To restart search a macro statement, turn the control parameter "Macro single" ON, and
execute restart search.
Note that due to the radius compensation, corner R/C or geometric preread block, the tool
path may change.
2) The program No. cannot be omitted when carrying out a restart search.
If the program No. is omitted, an error occurs, and restart search cannot be executed. Set
the program No., and restart the operation.
3) When restart search is executed, the commands for S2 to S4 will all be input as S1 data.
4) If the N or B Nos. are not set, the other numbers not set are ignored.
5) If the menu key
