In the class of Ornstein transformations the mixing property satisfies a 0-1 law. Here we consider Ornstein’s construction with bounded cutting parameter. In fact, these latter transformations are not mixing, however it is proved that the weak mixing property occurs with probability one. Our situation is similar to the case of interval exchange transformations whose link with the cutting and st...

The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

This paper contains investigations on the behavior of five artificial rocklike materials subjected to abrasive water jet cutting. The influence of the test parameters, i.e. applied pump pressure, traverse rate and abrasive mass flow rate was investigated, as well as the influence of several material parameters, e.g. compressive strength, Young's modulus, absorbed fracture energy and crack veloc...

In order to provide the basis for design and control of a citrus picking robot clamp cutter, find optimal combination cutting parameters, this study used self-made stem test-bed effects diameter, blade speed, clearance, tool sliding angle on peak force stems through single-factor experiment. Based test, are selected as influencing factors, multi-factor test is carried out with target force, reg...

Rock abrasivity is an essential factor for selecting cutting tools, estimating tool wear and life, and ultimately, matching various mechanized excavation systems with a given geologic condition. It also assists engineers to determine economic limits of different cutting tools and machines used in civil and mining projects. The Cerchar abrasion test is a simple and most widely used method for ro...

the influence of 0-27 g/100g of full-fat soy flour (ffsf), 31-35g/100g of water content and extrusion conditions on the textural characteristics of spaghetti were evaluated. process was performed with screw speed of 10-40 rpm and water circulating temperature of 35-70°c. this enrichment resulted in significant differences in mechanical strength and cutting parameter. based on the mixture surfac...

The recently developed Doubly Linked Face List (DLFL) structure introduces a powerful modeling paradigm that allows users to alternatively apply topological change operations and subdivision operations on mesh structure. Moreover, the DLFL is topologically robust in the sense that it always guarantees valid 2-manifold surfaces. In this paper, we further study the relationship between DLFL struc...

Conventional machining is a form of subtractive manufacturing, in which a collection of material-working processes utilizing power-driven machine tools are used to remove undesired material to achieve a desired geometry. This paper presents an approach for comparison between turning center and vertical machining center by optimization of cutting parameters at cylindrical workpieces leading to m...
