Quick Summary

Photochemical machining (PCM) is a manufacturing process that uses photographic and chemical etching techniques to create components from various metals, particularly stainless steel. It is an extension of chemical machining (CHM).1

Machine tools are stationary, power-driven machines used to shape or form parts from materials like metal. They operate by removing excess material as chips, shearing, squeezing, or using electricity, ultrasound, or chemicals. Modern machine tools can achieve very high precision, with tolerances as fine as plus or minus one ten-thousandth of an inch.2
