Comparison of High Feed Machining with Conventional Milling in Terms of Dimension Accuracy and Productivity

Abstract

Numerous industrial enterprises are forced to increase productivity if they want to stay competitive in the market. Therefore, there were performed many researches focused on possibilities of cost effective increasing the productivity. There were created advanced processes and new machining strategies, which could be improved by new cutting materials, advanced coatings and modified geometry. One of the cost effective methods to increase productivity is High Feed Machining (HFM). This method does not require high speed spindle (in contrast with High Speed Cutting -HSC). Moreover, it does not require any special devices or conditions. HFM can be performed on the modern machine tools. This article compares conventional milling and high feed machining of the reference steel materials -C45 by creating some basic shapes and features, such as horizontal and vertical surfaces, cylinders, grooves, etc. Results of the experiment could be applied to determine when HFM is advantageous and what advantages it brings about.

Comparison of High Feed Machining with Conventional Milling in Terms of Surface Quality and Productivity

“…For HFM, using of infeed with a value of half of the tool diameter is necessary due to the specific design of solid end mills. If there were compared tools according to the same infeed instead of the same shrink diameter, results of HFM could be even better [18].…”

The Tool Wear Observation of Milling Tools in High Feed Machining of Hardened Steels

“…The durability of high-feed tools due to the special shape of the cutting edge make them particularly interesting for structuring already tempered semi-finished tools [17]. The comparison of high feed machining with conventional milling in terms of dimension accuracy and productivity is presented in [18].…”
