FEM ANALYSIS OF THERMAL SOFTENING – INVESTIGATION OF THE INFLUENCE OF WORKPIECE TEMPERATURE ON CUTTING FORCE IN THE DEFORM ENVIRONMENT

This paper presents the findings from numerical modeling of the turning process of titanium alloys with preheating of the workpiece. This modelling was conducted using the DEFORM-2D software environment, which is based on the finite element method (FEM). The objective of this study is to investigate the influence of workpiece temperature on cutting force and to determine the optimal heating parameters for machining materials that are challenging to process.

Causes of degradation of titanium dental implants

Corrosion is one of the main processes that cause problems when using metal implants in the environment of the human body. Due to its properties, titanium and its alloys are currently the most widely used biocompatible materials. But the use of implants made of titanium-based alloys is not always successful. The purpose of our research was to establish the reasons for the rejection of a Swiss firm’s dental implant made of Grade 5 titanium alloy. Implanted in the patient’s jawbone, it worked as a support for an artificial tooth.
