In the roughing tool path S = r + T substitution on the type, the tool can be modified linear equations. Other graphics tool code-named route changes on this point is omitted,[link widoczny dla zalogowanych], no detail. Fourth,[link widoczny dla zalogowanych], tool selection and tool path workpiece in accordance with the roughing, semi-finishing and finishing the order carried out. Have to judge each piece to carry out a form and identify tools to be used. Because the tool in determining when, but also to determine the shape of the workpiece by the tool line. Therefore, tool selection and tool path have very close ties. In order to analyze the workpiece in the y direction, whether the shape change,[link widoczny dla zalogowanych], so, from i = 1 to n-2 input points Pi and Pi + l y-coordinates are compared,[link widoczny dla zalogowanych], and if Y ... <Yi, then we must determine the subsequent processing Tool 1 is available. That is, when the slope of line PiP ... Ai angle than the slope of the tool An associate of age, can not be carried out with a cutting tool to be supported by other tools to process. Figure 6 (a) is the occasion to be the tool 1,2, Figure 6 (b) as a tool a tool line, Figure 6 (c) the tool path for the tool 2. (C) Figure 6 Route Selection Tool (a) requires the tool 12 occasions (b) 1 line tool (C) 2 line on the roughing tool, the tool in the selection must also consider the route tool the feed position. Roughing tool by the end point the combination of lines and arcs to represent the rough tool path and tool change point position Y = A simultaneous equations obtained. Figure 6 shows the graphical model of the feed position. Calculated by the method of NC tool path must be transferred to the NC device to receive instructions, in the PT = 0, press the \for cutting. The 11th China International Mould Technology and Equipment Exhibition will be held in Shanghai The 11th China International Die branch surgery and Equipment Exhibition will be held May 8, 2006 to 12 at the Shanghai New International Expo Center. The exhibits range: mold and mold products. Mold standard parts; processing center. The number of air milling, boring, turning, drilling and other metal cutting machine tools; various types of electric machines. Engraving machine; coordinate measuring machines and other measuring equipment, etc.; 1, 2006 die-casting machine, various types of pressure equipment, machine tools and test mode; plastic machinery and rubber machinery; mold materials, metallurgical products; mold CAD, CAM, CAE; used in various types of mold materials, auxiliary equipment. Including polishing, grinding, assembly fixtures, etc.; tools, cutlery and other products associated with the mold. * 55 * salamander
