Warm single-point incremental forming (SPIF) has been proposed for those sheet metals with poor formability at room temperature such as magnesium alloy. This technology offers an alternative to meet the requirements of small batches and customization. However, the forming-induced orange peel effect is usually detected in the appearance of the AZ31 products in the warm SPIF. In this work, two heating systems, electric pipe heating and hot air heating, are respectively adopted for the warm SPIF process. The surface roughness and microstructure of the samples formed with the two heating systems are compared and evaluated for the sensitivity analysis of orange peel effect. In addition, the influence of process parameters including forming temperature, speed rate and step size on surface quality is also analysed. The results indicate that the orange peel effect and the corresponding microstructure development should be considered to improve the surface quality of magnesium alloy product.
