Lumber is produced from logs in the timber industry through a process called sawmilling. Logs are first debarked and then cut into various sizes and shapes using saws. The cut pieces are then dried and treated to improve their strength and durability. Finally, the lumber is sorted and graded based on quality before being shipped to customers for use in construction and other applications.
This industry includes establishments primarily engaged in sawing rough lumber and timber from logs and bolts, and separately operated planning mills.
In my world timber is still standing in the woods and is cut down into logs. Then the logs are taken to a sawmill and cut into lumber. Some places refer to timber as wood that has been cut from trees into a usable form, so a place where logs are cut into timber is a sawmill. (The word lumber has this meaning in North America.)
Lumbering means the cutting down of different trees of any forest for the extraction of wood and timber from the trees. The industry where the logs of the trees are transformed into furnitures and other wood products is called lumbering industry.
Lumber is made when logs are sawn into boards at a sawmill.
This term can refer to converting raw timber into dimensional lumber or to a set of formula used to convert the weight of various types of lumber to a volume.

Limber Timber
One of the various steps involved in lumbering is felling the trees. This is when they are cut down. Next trees must be debarked, after that the trees are cut into large logs, and then into smaller logs.
Oh, dude, a hink pink for flexible logs would be "bendy timber." It's like when those logs are all chill and can just bend and flex without breaking, you know? So, yeah, "bendy timber" is the technical term for those laid-back logs.
