Old Amada machines with Fanuc controllers have limited memory, which, can be an issue when you are punching or laser cutting and file size exceeds machine capacity.
Thankfully Amada has a Macro programming System, the macro function of whichhelps store the contents of multiple blocks of data within the memory of NC as a single macro data and it can be recalled whenever required. To store the data one has to enter a two-digit number from 01-99 preceding the address letter “U” or “V” for multiple and single block memory.
The two-digit numeral following “U” or “V” is called-the “macro number”. This macro number comes in three types–where the data between “U” AND “V” , One – remain stored while they are simultaneously being executed; two – only stored in memory; three – Storing of multiple macros is accomplished.
Multiple macros can be stored and recalled by using macro numbers 90 to 99. These macro numbers are only capable of defining a group of multiple macros as one Macro. They are unable to store execution instructions.
G98 LAYOUT FOR PUNCHING MULTIPLE PRODUCTS
Format:G98X . . . . Y . . . . I . . . . J . . . . P…K . . . .
X = Set up new “0” point (starting point) in the “X” axis.
Y = Set up new “0” point (starting point) in the “Y” axis.
I = Pitch between parts in “X” axis (including slotting tool)
J = Pitch between parts in “Y” axis (including slotting tool).
P = Number of spaces between parts in “X” axis.
K = Number of spaces between parts ‘7” axis.
Metacam can handle this function quite easily. In Metacam the layout has functions which can grid parts.
Keys points to be aware of
- Amada grid function doesn’t support the common line cutting, so gap between parts is mandatory.
- If reposition is required make sure 2 sets of grids are created.
