This thesis presents six optimization models which are developed and solved in two stages in order to integrate tolerancing and machining parameters decisions. One model is developed in the first stage. The first-stage model is related to a design problem and provides better part tolerance to be used in the second stage to incorporate tool adjustment decisions into the optimization of machining parameters. Five models are developed in the second stage and are divided into single-machine and multi-machine turning operation problems. For single-machine turning operations, three models are formul

Stabilitet och vibrationer inom invändiga svarvningsprocesser är ett område som kräver mer forskning. Tidigare studier visar att problem med stabilitet och utböjning är vanligt vid dessa processer och att de orsakar oönskade vibrationer i processen. Vibrationerna har en negativ effekt på bland annat ytjämnheten, som har visat sig vara en viktig parameter vid invändig svarvning. Syftet med den här studien var därför bland annat varit att undersöka utifrån vilka olika skärparametrar en konstruktions stabilitet kan säkerställas för att uppnå kravspecificerad ytjämnhet.

The primary objective in machining operations is to produce products with low cost and high quality. Machining parameter optimization plays an important role in achieving this goal. Machining parameter optimization in multi-pass machining operations usually involves the optimal selection of cutting speed, feed rate, depth of cut and the number of passes. In this thesis, the parameter optimization problem for multi-pass machining operations is studied.

Turning is one the most important machining operation in industries. The process of turning is influenced by many factors such as the cutting velocity, feed rate, depth of cut, geometry of cutting tool cutting conditions etc. The finished product with desired attributes of size, shape, and surface roughness and cutting forces developed are functions of these input parameters. Properties wear resistance, fatigue strength, coefficient of friction, lubrication, wear rate and corrosion resistance of the machined parts are greatly influenced by surface roughness.

In order to solve this problem, tool manufacturers have developed anti-vibration tools to suppress the vibration generated during cutting. Compare

Over the years, numerous attempts have been made to fabricate these molds using various approaches such as lithography, FIB, laser ablation, and precision diamond turning. Amongst these approaches, diamond turning is by far the most commonly used method to generate the micro-patterned rollers for roll-to-roll fabricating of precision optical parts such as BEF and 3D fi
