Abstract

The spindle collet, a critical component in various machine tools, plays a pivotal role in determining the success of machining operations. This paper aims to study the static and dynamic parameters of collet structures made from three different materials using the finite element method. A three-dimensional model and computer simulation were conducted in Autodesk Inventor software. Simulations are performed using identical boundary conditions and mesh size. Static analysis is performed with varied applied forces where total deformation and Von Mises stress are measured. For the dynamic analysis, the natural frequencies and mode shapes are measured up to the first five modes. The variations in stress is minimal when the material is altered. The magnitude of deformation varies significantly with changes in material. The relative deformation values demonstrate that carbon steel deforms more than alloy steel by almost 3%, while stainless steel deforms more than alloy steel by 6%. Materials with higher Young's modulus and lower density have been found to increase the natural frequencies, reducing total deformation and von Misses stress. The use of alloy steel in the industry offers an advantage over the other two materials. The results provide improved insight into the appropriate materials for the collet.

Abstract

Over the years, there has been a strong emphasis on predicting the dynamic behavior of machine tool structures by identifying modal parameters. The machine bed is one of the most significant components in a CNC milling machine because its functionality significantly affects the final product's quality. The bed acts as the machine's foundation, supporting all of the machine's critical components. It is also utilized to avoid deformation caused by static and dynamic loads. This study aims to compare the modal parameters of several alloys used as bed materials, such as carbon steel, alloy steel, and stainless steel, to those of a common material. A three-dimensional model and modal analysis of the bed were conducted in Autodesk Inventor software. Alloy steel shows the highest values of natural frequencies compared to other materials due to its high Young’s modulus and low density. Similar mode shape is observed with varied magnitude in all the materials. According to the findings, alloy steel could be a viable alternative to cast iron in machine tools bed's structure
