The temperature rise exceeds over 1000°C in cutting process while working with PCBN tools high speed machining. This intense temperature results in wearing of tools and thus diffusion and oxidation are mainly responsible for wearing. This paper proposes the oxidation and diffusion wearing for PCBN cutting tools and analysis has been carried out considering thermodynamics principles. The next st...

Linear ball guideways (LBGs) have several advantages for the precise positioning control of machine tools. However, ball-groove contact behaviour leads to poor dynamic compliance, which induces a significant nonlinear guideway and chatter stability. The nonlinearity complicates prediction due dependence stiffness. This approach aims offer an industrially orientated method estimation stability s...

THIs implant was developed with the object ofincreasing the degree ofmovement obtained with the Allen type ofburied orbital implant. The satisfactory way in which these implants are retained in the orbit is demonstrated by the large number which have now more than fulfilled the 2-year follow-up period suggested by Choyce (1952). The retention of the magnetic form of implant appears to be as goo...

In this study, an experimental approach is presented for the measurement of the surface roughness of the machined surface produced by simple turning operation in a computer numerically controlled (CNC) Lathe. The parameters used in the experiment were reduced to three cutting parameters, cutting speed, depth of cut, feed rate. Other parameters such as tool nose radius, workpiece length, workpie...

The purpose of this research is to investigate appropriate collaborative forecasting models, both for acceptable accuracy and effectiveness for information sharing via the Internet to partners. Several forecasting models were investigated in this research. For comparing the models, five years historical data are collected from a lathe machine manufacturer in Taiwan, and one of its partners – a ...

The effect of forming parameters during the incremental sheet forming process (ISF) was studied for a circular shape sheet part. ISF is known as a rapid prototyping method to produce sheet metal parts in a batch production series. ISF has found to be useful and advantageous which increases its application in industry. A CNC lathe machine was used in this study because it was easily programmed t...

A tool remaining useful life prediction method based on a non-homogeneous Poisson process and Weibull proportional hazard model (WPHM) is proposed, taking into account the grinding repair of machine tools during operation. The intrinsic failure rate built according to data. WPHM established by collecting vibration information operation introducing covariates describe In combination with repair,...

The packaging is an activity that aims to increase selling value and protect products from damage the environment. Packaging automatically uses a machine amount of production. machines have very expensive prices so it burdensome for UMKM who want do business in this field. This research will make cooking oil with capacity 15 pcs / minute. Making requires machining process including welding proc...
