A novel investigation on effect of process parameters on cylindricity tolerance while drilling normalized and annealed SAE 304 stainless steel and comparing the outputs with untreated stainless steel.

The overarching purpose of this study is to compare the cylindricity tolerance findings obtained from drilling in heat-treated stainless steel to those acquired from drilling in normalised and annealed stainless steel, as well as the results obtained from drilling in untreated stainless steel. Substances and Techniques: The research used 12-mm thick stainless steel plates. Stainless steel plates go through normalisation and annealing at temperatures of 750 and 850 degrees Celsius. Drilling research CNC vertical milling centre. Because of its longevity, tungsten carbide drill bits are often favoured. ASTM standards were used for cylinder tolerance testing and inspections. Calculating the sample size at 80% of the pretest power. Twenty samples were collected from each of the study and control plates. Results: When comparing the three classes, the Untreated Stainless steel had the highest surface roughness, as determined by a one-way analysis of variance (ANOVA) performed using SPSS tools. The significance threshold was determined to be 0.001 after running all of the data through SPSS to determine it and then seeing the resulting graphs. (p0.05). It was concluded that, within the limits of the experiment, heat treatment resulted in a significant increase in attributes that improved mechanical characteristics and boosted process parameters.
