Evaluation of the cutting force and geometric error for roughing operation by plunge milling

Nowadays there has been noticeable an expressive technological development in the cutting process to machine moulds and dies, through applying new materials, cutting tools and machining strategies. The rough operations depict an important portion in the machining time of these pieces. In front of this scenario, a new milling rough operation in the tool's axial direction represents a possibility to optimize this machining process so as decreasing the machining time and increasing the material removes rates. A few scientific studies have been carrying out at this thematic, limited to a technical-commercial researches. Therefore this work contributes with the knowledge in this machining process through an experimental trial analyses. In special it studies the cut direction effects during climb and conventional milling in these operations. The result quantifies the cutting parameters influence at the cutting force and error form.
