Comments
This V6 block project had a serial process. Makino provided process stages Op10B, Op40B, Op50B, Op30MA and Op40MA. Stages 20B, 10MA, 20MB, 50MA, 60MA and 70MA were supplied by other vendors.

Machining systems must be agile, yet be operated by shop floor personnel. Makino is responsible for much of the shop floor integration.

An interim process was also provided for the block’s lower case. This featured high-speed bulk head milling.
