Abstract：

The effect of process parameters on the formability of 6061 aluminum alloy sheet was investigated by the ordinary single-point incremental forming technology. The orthogonal experiment method was used to investigate the effects of four process parameters such as Z-axis layer feeding amount, feeding speed, tool head diameter and lubrication method on the formability of 6061 aluminum alloy sheet. Combining the range analysis and variance analysis, the influence order of the four process parameters on the forming limit angle and the significant influence level of formability were studied. The results show that the tool head diameter is the biggest factor affecting the formability of 6061 aluminum alloy sheet, followed by the lubrication method, feeding speed and Z-axis layer feeding amount. From the range analysis, a set of optimal parameter combination of A2B2C1D3 is obtained, and the maximum forming limit angle is 82.78°. From the variance analysis, it is known that the tool head diameter has a significant influence on the formability among the four process parameters. This result is consistent with the range analysis result.
