Achieving Accuracy Improvements for Single-Point Incremental Forming Process Using a Circumferential Hammering Tool

The paper presents a novel solution for improving the accuracy of wall area parts manufactured by single point incremental forming. Thus, forming tool with special design that works according to principle circumferential hammering is deployed, direct effect conditions and consequently dimensional part. research focused on an experimental study frustum-of-cone shapes from sheet metal blanks DC05 deep drawing steel 1 mm thickness. A typical customary technological setup used process, without any additional elements, two tools, hemispherical one, which use effect. Several preliminary tests using both tools were performed in order prove part can be significantly improved tool. was further expanded investigate influence three factors: spindle speed, feed rate configuration. Using full factorial plan experiments results 32 test runs processed. All machined adequately, free material fracturing. Based achieved machining walls, precision mathematical models developed prediction those areas. validated practice, as predicted accuracies matched results.
