The present paper consists in a comparison of vibrations measured during face milling cutting with two constructive variants of milling cutters (one with classic insert clamping and other with a quick insert adjustment mechanism). The goal of the study is to determine if the new clamping mechanism of the inserts has a similar behaviour with the classic one and can withstand milling conditions without introducing additional vibrations in the system
The paper consists in a research in the design of an innovative face-milling cutter, in terms of product lifecycle management (PLM), with the help from creative design methods, such as TRIZ. The model of the lifecycle management of the cutting tools was presented, emphasizing the functional analysis and creative design phase. Based on this analysis, a new constructive variant of the milling cutter was designed and simulated with finite element method, highlighting its advantages compared with classic construction variants.
The paper consists of a research in designing and experimental analysis using a face milling cutter with round inserts. A general model for the new cutter is proposed taking into consideration multiple aspects regarding monitoring and controling the milling process. A comparison of measured vibrations when cutting with different parameters for two constructions of the milling head is presented. The objective of this vibration comparison is to verify wether the new design behaves in similar way with the classic and proven concept of insert clamping using a central screw.
The paper presents a conceptual model that pursues the understanding of the activities, the phases and the mechanisms of product design. The purpose of this model is to aid the product conception phase, as well as to develop software products that can furthermore aid design. The model takes into account the entire mental potential of the human being. The paper uses Jung's model in order to describe the various aspects of the human psyche. The paper presents a number of design models from the scientific literature. The proposed model defines domains of the needs imposed by stakeholders and specialists, functions domains and product domains. It explains the mechanism through which information is passed from one domain to another. As the information travels between domains, it undergoes a series of modelling and objectivation processes. The model is explained in better detail for the first phase of product design; however, it is applicable in all phases of product lifecycle. In the space and time coordinates used by the model, the conception appears as a spiral.
