If a food bears a USDA Organic label, it means it's produced and processed according to the USDA standards. The seal is voluntary, but many organic producers use it. Products certified 95 percent or more organic may display this USDA seal.
A machinist is a person who uses machine tools to make or modify parts, primarily metal parts. This process of machining is accomplished by using machine tools to cut away excess material much as a woodcarver cuts away excess wood to produce his work.
Once these programs are developed, CNC machines follow the set of instructions contained in the program to produce the part. Machinists normally operate CNC machines, but tool and die makers often are trained to both operate CNC machines and write CNC programs and thus may do either task.
