“…20 Loads acting on the roll and chuck in the skew rolling process of a hook preform conducted in a CNC rolling mill Fig. 21 Torque on one of the rolls in the skew rolling process of a hook preform conducted in a CNC rolling mill steel billets were preheated to a temperature of 1150 °C in an electric furnace. This temperature was lower than that used in the numerical analysis because the experiments were limited to rolling preforms, without performing the forging process.…”

“…Nevertheless, there still exist problems with flexible manufacturing systems for producing solid parts by processes such as forging and rolling. In recent years studies on CNC skew rolling have been undertaken [21]. This technique can make it possible to implement flexible production of axisymmetric parts such as preforms, and it addresses the needs of a flexible manufacturing system.…”

This paper relates to a study on the formation of elongated preforms in a CNC skew rolling mill. First, a numerical analysis was performed to investigate forming processes for three different parts: a scraper, a connecting rod, and a hook. The shapes and dimensions of preforms were designed, and rolling and closed-died forging processes for producing these parts were simulated numerically. Distributions of temperature, effective strain and damage function were determined for rolled preforms. Loads and torques in the rolling process were measured. It was found that the forming process of preforms performed in a CNC skew rolling mill was characterized by relatively low force parameters in relation to the dimensions of formed parts. Numerical simulations of the forging process showed that all forged parts had the required shape, which indicates that the preforms were designed correctly. Following the numerical analysis, experiments were performed in which the preforms were rolled under laboratory conditions (in a scale of 1:2). Experimental results demonstrated that the rolled parts had no internal defects (cracks) and were characterized by high dimensional accuracy.
