Many people use the term machine and tool interchangeably.
So what is the difference. The motor mechanism is what puts movement into the parts of the machine, the transmitting mechanism, such as toothed wheels and pulleys etc. The tool is that part of the machine that moves, due to the other two parts, and helps to produce a given commodity. A tool in this sense is different from the tool of a workman. A workman might use a hammer or a chisel but they are tools not machinery.
