“…During the photochemical degradation of the metal, heavy metal ions such as Pb 2þ , classified as toxic and carcinogens by International Agency for Research on Cancer (IARC), can be generated depending on the process and material characteristics (Sobhanan et al, 2020). For many available and common metals and alloys, the available thickness range and the maximum processable sheet size for the PCM process are generally limited to 0.013-2.03 mm and 300 3 600 mm 2 , respectively (AME, 2022;Centre Circuits Chemcut, n.d.;Vyas et al, 2021). Despite their low costs, chemical etchants utilized during the process should be recovered or safely disposed of from environmental aspects, which increases the operational cost of manufacturing to maintain their hazardous emissions levels below the limits of regulations and standards (Patil and Chapgaon, 2019).…”

PurposeThe purpose of the paper is to investigate photochemical machining characteristics of stainless steel (AISI 304-SS304) parts with a novel design are investigated experimentally from the aspect of process parameters. The effects of phototool pattern geometry, ultraviole (UV) exposure time and etching time on of AISI 304 were evaluated.Design/methodology/approachThe designed semi-automated photochemical manufacturing (PCM) equipment consists of 4 units, which include UV exposure, etching, developing and surface cleaning units. Experimental procedure has been designed via Taguchi method. Results were evaluated via Analysis of Variance (ANOVA) method.FindingsEtching time is the most effective factor in PCM quality of AISI 304 stainless steel. Surface roughness is sensitive to geometrical pattern of the phototool for PCM of AISI 304 UV exposure time is less influential on the PCM quality for stainless steel.Research limitations/implicationsThe designed PCM equipment prototype is not fully automated, which requires automation for part replacements into units. The effects of the temperature inside chemical processing units on process characteristics cannot be evaluated due to equipment limitations. The effects of surface cleaning time inside surface cleaning unit are not analyzed.Originality/valueThe utilized PCM equipment is semi-automated equipment, with which the process parameters such as etching time, surface cleaning time, UV exposure time and developing time can be controlled. Different from literature, the effects of phototool pattern geometries on the photochemical machining quality parameters are evaluated for the processing of AISI 304. The effects of processing parameters on dimensional accuracy, which is not common in the literature for AISI 304 stainless steel, are also evaluated.
