Determination of the Cutting Moments at Teeth Tip in the Case of the Milling Cutter with Multiple Teeth

Abstract

This paper presents experimental results for milling process using a six components dynamometer for complete mechanical actions measurement. The aim is the cutting moments determination and their evaluation on the milling cutter with multiple teeth during the cutting process. To know the cutting moments to the teeth of the tool, the instantaneous position of the teeth during milling process is determined. To achieve this purpose a calculation algorithm was developed to obtain the milling cutter teeth position respectively the moments at the tips of the teeth.

Three-Stage Shear-Serrated Aerator Broke CO2 Bubbles To Promote Mass Transfer and Microalgal Growth

“…When gas flowed in the direction of the conical head, the probability of cutting by the conical head increased considerably. Increased sawtooth height indicated a greater momentum with an improved mixing effect of mixing when the bubble moved away from the aerator . Therefore, the third-cutting effect of the aerator on bubbles was more apparent and led to the generation of smaller bubbles.…”

A 6-components mechanistic model of cutting forces and moments in milling

“…In the context of machining, the hypothesis of undeformable solids is used because the forces and moments components of the energy balance are measured and global. The internal mechanical power developed by machining, calculated at the point P, is then described [12][13][14]:…”

“…Mechanical models have to consider the 3 forces and 3 moments components especially in machining as hard cutting processes or high-speed machining [12]. For these configurations, the contribution of the cutting moments constitutes an important part of the consumed energy in machining and can be as high as 40% for conventional machining and up to 80% for high-speed machining [12][13][14].…”
