Manufacturing of the tensile test specimens with minimal surface defects and close tolerances are the key factors to achieve desirable and accurate mechanical properties. In addition, faster and cost-effective manufacturing methods with reliable results are also critical requirements. This study focuses on determination of the effects of various manufacturing methods on tensile properties and surface conditions produced during different machining operations. For this purpose, tensile test specimens of S700MC steel were prepared in rolling directions of 0 degrees, 45 degrees, and 90 degrees using wire electro-discharge machining (WEDM), abrasive water jet cutting (AWJC), plasma cutting (PC), laser cutting (LC), and milling operations. The results were discussed in terms of specimen dimensions, surface roughness, (Ra and Rz) and tensile properties in detail.
