Preparation time depends on material hardness, specimen dimensions, and the number of cuts required. For most metals, a standard specimen can be completed in 5 to 15 minutes, including loading, machining, and finishing. Softer materials or small-batch jobs take less time, while hard alloys or high-precision samples may require additional passes. Systems with automated clamping and preprogrammed standards help reduce handling time and keep production flow consistent across testing schedules.
