Incomplete mesh offset for NC machining
In this paper, the incomplete triangular mesh including reversed faces and gaps between boundary edges is directly offset for NC machining. or three-axis machining, vertical faces are deleted and the face normal vectors directing the lower part of model are changed to upward. The omplete mesh is offset by the multiple normal vectors of a vertex, and boundary edges and boundary vertices are offs...
متن کاملA framework for machining optimisation based on STEP-NC
Inappropriate machining conditions such as cutting forces cause tool failures, poor surface quality and worst of all machine breakdowns. This may be avoided by using optimal machining parameters, e.g. feed-rate, and continuing to monitor it throughout the machining process. To optimize feed-rate, we propose a system that consists of an optimisation module, a process control module and a knowled...
متن کاملPrecise global collision detection in multi-axis NC-machining
We introduce a new approach to the problem of collision detection in multi-axis NC-machining. Due to the directional nature (tool axis) of multi-axis NC-machining, space subdivision techniques are adopted from ray-tracing algorithms and extended to suit the peculiarities of the problem in hand. We exploit the axial-symmetry inherent in the tool's rotational motion to derive a highly precise pol...
متن کاملOn-Line Optimization of Cutting Conditions for NC Machining
This paper discusses a number of discrete models used for optimization of cutting condition during NC machining. The models can be broadly placed into two categories: 1. volumetric models in which feedrate is proportional to either average or instantaneous volumetric removal rate, 2. vector force models in which feedrate is set to values which keep either average or instantaneous cutting forces...
متن کاملHigh-quality NC-data Generation in Mold and Die Manufacturing
The CAM operation which generates a process plan and NC-data for mold machining plays an important role in mold manufacturing because it quite affects down stream processes such as NC machining, polishing, and assembly operation. This study proposes a supporting system which facilitates non-experts to perform the CAM operation easily and to select the high-quality NC-data which can increase mac...
