To support the rapid development of pen-based structured diagram editors, we propose a framework for describing such editors. The framework uses grammar to describe the context, i.e., the positional relationship between handwritten strokes and other objects, which can be used to interpret ambiguous results of pattern matching, and to describe the syntax of the target diagrams. We implemented th...

We present a hardware-software cosimulation environment for heterogeneous systems. To be an efficient system verification environment for the rapid prototyping of heterogeneous systems, the environment provides following features: interface transparency, smooth transition to cosynthesis, simulation acceleration, and integrated user interface and internal representation. Among them, the first tw...

A new approach to the refixturing-free sculpturing of large, arbitrarily complex shapes has been developed. Based on an enhanced accessibility analysis of the target shape, a reduced set of candidate machining orientations is determined. Then, machining takes place at very close distance between the tooling machinery and the part, thus achieving effective material removal in complex regions. Mi...

Paper presents research results of the parts accuracy after manufacturing with used Rapid Prototyping technology in context of the possible use of multi-directional layers disposition. Errors of the model by production were analyzed in two categories: external and internal model errors. External errors of models production include: conversion error, staircase error and error of slicing into lay...

We propose in the paper a process, based on the use of a high velocity, electric arc metal spray thoroughly atomized on a master model in order to make a shell. The mold is realized by placing the sprayed alloy into a frame and reinforcing it with appropriate material. The first part of the paper presents briefly the main rapid prototyping and tooling techniques used in industry. We then descri...

Rapid Prototyping (RP) presents the automatic production of physical parts using by additive manufacturing technology. The start techniques for Rapid Prototyping became available in the late 1980s and were used to produce models and prototype parts. Today they are used for a much wider range of applications and are even used to manufacture productionquality parts in relatively small numbers. Ra...

The term prototyping has in recent years become a buzzword in both research and practice of system design due to a number of claimed advantages of prototyping techniques over traditional specification techniques. In particular it is often stated that prototyping facilitates the users' involvement in the development process. But prototyping does not automatically imply active user involvement! T...
