Abstract:

Asphalt and concrete reclamation machines are used to cut roadways when a repair is required. The performance of these machines can affect the quality of road repairs, and cost/profitability for both contractors and governments. We believe that several performance characteristics in reclamation machines are governed by the placement and pattern of cutting picks on the cutter head. Previous studies, focused on mining and excavation applications, have shown strong correlation between placement and wear. The following study employs a screening experiment (observational study) to find significant

Abstract:

Developing a means of predicting tool life has been and continues to be a focus of much research effort. A common experience in attempting to replicate such efforts is an inability to achieve the levels of agreement between theory and practice of the original researcher or to extrapolate the work to different materials or cutting conditions to those originally used. This thesis sets out to examine why most equations or models when replicated do not give good agreements. One reason which was found is that researchers in wear prediction, their predictions are limited because they generally fail

The requirement for improved dimensional accuracy to achieve ever tightening tolerances in manufactured parts increases the need for high precision machine tools. Machine tool accuracy is affected by various errors from which thermal errors have been identified as one of the largest contributors. These are primarily caused by heat generated by the machine as it operates and exogenous influences, mainly in the form of varying environmental temperature, that result in deformation of the machine structure. There is a complex interaction between the structural components having different heat sour

Now efforts are being made to further reduce the time and cost of measurement by reducing the physical distance between machining and measuring processes.

Five-axis CNC milling machine tools bring great facility to produce complex workpieces with increased dimensional accuracy and better surface quality in shorter machining times. However, kinematics of five-axis machine tools has a complex form which makes it difficult to operate these machine tools properly. The difficulty arises from the complexity of NC-Code generation and tool path verification. Collision of machine tool or setup components with each other is a severe problem in five-axis machining operations and usually results from inadequate postprocessors or insufficient collision check
