Modeling of Turn-milling Process
This paper presents an analytical approach for modeling of turn-milling which is a promising cutting process combining two conventional machining operations; turning and milling. This relatively new technology could be an alternative to turning for improved productivity in many applications but especially in cases involving hard-to-machine material or large work diameter. Intermittent nature of...
متن کاملAbstract Milling with Turn Costs
The Abstract Milling problem is a natural and quite general graph-theoretic model for geometric milling problems. Given a graph, one asks for a walk that covers all its vertices with a minimum number of turns, as specified in the graph model by a 0/1 turncost function fx at each vertex x giving, for each ordered pair of edges (e, f) incident at x, the turn cost at x of a walk that enters the ve...
متن کاملThe Modular Design of Turn-milling CNC for Special Stones
Abstract Stone products' processing technologies, processes and types have essential differences with metal's, which makes the traditional machine design method, cannot perform well in the design of processing equipment for special shaped stones. A new design method was used in this paper, which through the establishment of stone typical products and tool mathematical model. The need of the mot...

We present the design and implementation of Arachne, a threads system that can be interfaced with a communications library for multi-threaded distributed computations. In particular, Arachne supports thread migration between heterogeneous platforms, with dynamic stack size management and recursive thread functions. Arachne is eecient, exible and portable | it is based entirely on C and C++. To ...

Given a 3-axis cutter motion we ask for a geometric representation of the resulting surface. Our discrete solution starts with a regular array of height values initialized e.g. to some constant value. The cutter is positioned at each array element of the scan-converted motion path, and the heights of the elements in the array covered by the cutter are decreased according to the cutter's geometr...
