5-Axis Test-Piece – Influence of Machining Position
نویسندگان
چکیده
Square pyramid and conical test-pieces have been machined. Disadvantages of square pyramid in respect to conical test-piece have been shown. Following the proposal of Bossoni [1], ISO presents a test-piece for simultaneous, 5-axis movement in ISO/DIS 10791-7 [4] without specifying the exact position and orientation of the test-piece. Therefore in this paper, test-pieces milled at four different positions on a 5-axis machining center are analyzed and the results are compared with kinematic simulations. It is shown by simulation and machining, that the accuracy of the test-pieces depends not only on the geometric characteristics of the machine tool, but also on the position and orientation of the test-piece.

The aim of this research work is to evaluate the effects of coolant including nano- powder material for the cooling purpose in milling process and comparing the results with the conventional coolant. Generation heat and weak heat transfer reduces the tool life and also deteriorate surface roughness during milling operation. To overcome this problem, it is necessary to use coolant for cooling as...

متن کاملModel for the prediction of 3D surface topography in 5-axis milling
The paper deals with the prediction of the 3D surface topography obtained in 5-axis milling in function of the machining conditions. For this purpose, a simulation model for the prediction of machined surface patterns is developed based on the well-known N-buffer method. As in sculptured surface machining the feed rates locally vary, the proposed model can be coupled to a feed rate prediction m...
متن کاملGraphics-assisted Rolling Ball Method for 5-axis surface machining
In this paper, a graphics hardware-assisted approach to 5-axis surface machining is presented that builds upon a tool positioning strategy named the Rolling Ball Method presented in an earlier paper by the present authors [Comput. Aided Des. 35 (2003) 347]. The depth buffer of the computer’s graphics card is used to compute the data needed for the Rolling Ball Method, which generates gouge-free...

After Gough [1] and Stewart [2] in the 50's and 60's introducing the idea of ‘hexapods’ (6-dof) [3][4], Clavel and his Delta structure [5] in the late 80's opened a new era with machines able to reach extremely high performances, used first for pick-and-place operations, and more recently for 3 or 5-axis machining. Considering the machining of complex shape objects, the solution often proposed ...
