AB/AB METHOD.Front and back side operation with one 180 degree carrier index. |
Front side by OP1, part reversed during load/unload sequence, Back side by OP2. OP1 and OP2 are independently
machined at the same time. AB/AB method most effective when the OP1 and OP2 cutting times are close or indentical.

AA/AA METHOD.Twin single operation parts with one 180 degree carrier index. |
Two single operation parts are loaded/unloaded and machined simultaneously. AA/AA method is applied when only
machining one side.

AA/BB METHOD.Twin front and back side operation with two 180 degree carrier indexes. |
Two front sides machined simultaneously by OP1, both parts reversed during load/unload sequence, two back sides
machined simultaneously by OP2. With this method two parts are completed every other carrier index. AA/BB method is
effective if the OP1 and OP2 cutting times are unbalanced and sufficient tooling for both OPs can be mounted in each
turret.

AA/A'A' METHOD.Split process of twin single operation parts with 90 degree carrier index. |
The machining process is divided into OP1 (roughing) and OP2 (finishing) of one single operation part. AA/A'A' method is
employed when the number of turret stations is insufficient.
|
|

AB/CD METHOD.Multiple operations on one machine with two 180 degree carrier indexes. |
The machining process is divided into four operations; OP1, OP2, OP3, and OP4. The AB/CD method provides one completed
part every other carrier index and is effective for multi-process operations.
