Other processes require elaborate and expensive machine tools. Tooling for photochemical machining is done primarily through a series of photographic steps reducing tooling costs yet achieving higher accuracy. Tooling cost can be as little as 1/10th of that required for other processes . since there are no cutting tools hence no wear and tear of the tools (millionth part is identical to the first) by means of which maintenance cost of tools is totally eliminated.

Due to the nature of tooling, lead-time from design approval to finished parts is cut down to only a few days. so photochemical etching process can save you thousands of rupees by delivering the parts much faster, than by any other method.

Parts Whose design is too complex and irregular and therefore, "impossible or uneconomical" to produce with standard manufacturing techniques ,can be produced just as easily, quickly and effectively as simple ones. Thus photochemical Machining provides unlimited design flexibility.

Photochemical process does not affect the molecular structure of the metal i.e. No strains or stresses are induced. Furthermore the process does not alter the hardness, grain structure or ductility of the metal worked.

A change in design means no more than a change in the drawing and film. Design changes are easily made at low cost, saving great losses due to obsolete tooling as in other process.

Since blanking is achieved "chemically" rather than mechanically, all finished parts are completely burr free and as flat as the parent metal from which they are manufactured.

Due to low tooling cost and fastest method for developing tools photo chemically machining is the most suitable process for prototype production and short runs. This would reduce the R & D cost drastically.
