Abstract

An integrated free-form-shape design and manufacturing system has been developed. The system runs on an engineering workstation with a 3D color display. It provides various means for designers to input their ideas and to modify them to develop an aesthetically pleasing free-form shape. The shape can be examined using a variety of display techniques, and the system automatically generates collision-free tool paths for rough and fine cuts from the designed shape, taking into account engineering factors such as heat-shrinkage compensation of the material used, and the gap compensation of electrodes.

Influence of pocket geometry and tool path strategy in pocket milling of UNS A96063 alloy
2013, Procedia Engineering
2½-D pocketing is a frequent operation in aeronautic and automotive industries. The path that must be followed by the tool during the milling process can be generated using different strategies. In the present paper, the influence of strategy and pocket geometry in parameters as machining time, cutting forces generated and surface roughness is studied. The pocketing tests have been performed on UNS A96063, an increasingly important alloy in such industries.
A tool path generation strategy for three-axis ball-end milling of free-form surfaces
2008, Journal of Materials Processing Technology
Recently, polyhedral machining method has regained attention from NC programming software developers. Furthermore, the polyhedral model is becoming popular as a data exchange medium between different CAD/CAM systems. This paper presents a new method for tool path generation based on the following algorithms: The free-form surfaces are approximated by triangular meshes. The vertices of triangular meshes are offsetted along surface normal. All offset vertices are then connected to form offset triangular meshes on which are sliced by a group of planes to obtain tool paths. Computer implementations and illustrative examples are also presented in this paper. The proposed method can be used to improve and automate three-axis free-form surfaces machining for CAD/CAM systems.
A geometric approach to boundary-conformed toolpath generation

Machining toolpath generation for free-form surfaces has been studied extensively. The major types of methods include the isoparametric method [1–3], isoscallop height method [4–6], isoplanar method [7–11], and isophote method [12,13]. Among the various methods, the isoparametric and isoplanar methods are the most popular techniques that are supported by commercial CAD/CAM systems [14].
Isoparametric or streamline-like toolpath generation is an important method for CNC surface machining. For a trimmed surface, the generation of such a toolpath is not straightforward because by simply following the isoparametric curves of the parametric surface to generate the toolpath, the resulting toolpath may no longer conform to the trimmed boundary of the surface. Various methods have been proposed to solve this problem. Some methods work well for single surface machining, but may not be feasible for multi-patch surface machining. A new geometric approach to the problem of multi-patch machining is proposed in this paper. The new method works by generating bisectors to partition the region into smaller subregions, and generates the toolpath by offsetting the subregion boundary by using a special offset function. As this new method does not rely on processing on the parametric domain of the surface patches, it can be used for both NURBS and subdivision surfaces. Examples are given to demonstrate the capability of the new method, and to show that the new method compares favorably with existing techniques.
Computing constant offsets of a NURBS B-Rep
2003, CAD Computer Aided Design
An approach for the automatic offset of a NURBS B-Rep has been presented which can be used for a class of manifold B-Reps. The approach offsets each of the trimmed surfaces (faces) of the B-Rep and then removes the gaps and intersections between offset faces automatically, if any. The offset B-Rep is then created by sewing all the updated offset faces. The practical approach and the treatment of the subject presented are unique and have not been reported earlier. The approach works under the assumption that the number of faces in both base and offset B-Reps is the same. It further assumes that the faces are at least G₁ continuous and non-self intersecting after constant offset. The present approach has given accurate and robust offsets of many lay-up surfaces (B-Reps) in the composite laminate modeling. The approach has better error control. Some of the offsets of lay-up surfaces that are generated using this approach have been presented.
Computing offsets of trimmed NURBS surfaces

All these approaches deal with offsetting of either a single curve or a single surface. Some of these algorithms deal with computation of non-self intersecting offsets of either curves or surfaces [6–8,10–13]. There is not much work, to the best of our knowledge, in the literature on offsetting of trimmed NURBS surfaces.
Offsetting of trimmed NURBS surfaces is one of the widely used functionalities in the design and manufacture simulations of composite laminates. This paper presents an approach for the offsetting of a trimmed NURBS surface. The approach has been developed mainly to meet the stringent accuracy requirements in the simulation of composite laminate design and manufacturing processes. However, the approach is applicable for the offset of a general trimmed NURBS surface. Though the method is based on known techniques in literature, the practical approach and the treatment of the subject presented is unique and has not been reported earlier. The basic approach consists of offsetting the underlying surface, offsetting of all the trimming loops and the creation of offset trimmed surface using the offset surface and the offset trimming loops. This is a unified offset approach for trimmed surfaces where in the offset of underlying surface and the offset of trimming loops are obtained using the same approach. The approach has better error control and results in less number of control points. Further the approach can be extended to obtain offsets of a general B-Rep. The approach has been used in the creation of offset surfaces of various aircraft components.
Algorithms to support point-based cadcam
2003, International Journal of Machine Tools and Manufacture
This paper presents a system that supports a point-based approach to CADCAM that was first suggested by McLaughlin. The core to the approach is the ability to interpolate a grid of points in a geometrically meaningful way that does not suffer from the disadvantages of the standard interpolation schemes based on NURBS. The essential features of the approach are based on recursive subdivision between existing points to generate intermediate points that are consistent with a smooth curvature profile. There are many advantages to this approach. Time-consuming surface fitting is not necessary; there are no problems with ensuring continuity between surfaces; data exchange can be carried out exactly. By chosing to work entirely with points, all of the standard interrogations available in CAE systems, including visualisations, FE analysis and NC machining, which are dependent on NURBS curves and surfaces have to be replicated. The feasibility of the point-based approach is illustrated by showing how geometric interrogations and machine tool paths can be accurately generated using just points.
