Abstract :
Development of the production process of an item begins with the use of human
labor until now it has used various kinds of machines as its main process.
Manufacturing process using a machine has a series of grooves throughout the
process so that it can be said in terms of the machining process. Machining process
using a base metal cutting is divided into the process of cutting by means of press,
traditional cutting with simple tools, as well as non-conventional cutting. Press
machines used to cut production materials often experience various kinds of
damage and failures during the production process. One of the most common
damages found on a press machine is a reversed flower groove, a disc disk chamber
that has a disposition, an incorrect setting of the blade, and an overhaul of the
flywheel bearing that is often troubled. Air flow or better known as airflow is
produced by a compressor engine so that it can channel compressed air to various
kinds of production machines through a sealing valve. Factors affecting valve
leakage are due to operator error that is not in accordance with the procedure. So
the solution for valve leakage is to replace conventional valves with selenoid
automatic valves.
