Figure 2 represents a geometric model of the mechanism from Fig. 1, where each parallelogram is represented as a obvious since coordinates frames {B} and {P} are always mutually parallel, i.e. Based on geometric relations shown in Fig. 2, the following equations are derived: Fig. 5 Experimental vertical milling machine prototype The initial point in conceiving the first vertical milling machine prototype has been the relationship between the The first step was to set the goals that can be summed up as follows: Fig. 7 Desktop milling machine CAD model The actuators are composed of step motors, leadscrews, and linear sliding guides. These are still widely used and superior in cost, reliability, and maintainability. (step motors, leadscrews, sliding guideways, joints, etc.) can be easily procured, that all other components can be built in a laboratory, and that control and programming system is based on PC Linux platform with real-time extension and EMC2 software system [7, 8]. Figure 10 presents a simplified structure of he control and programming system. The control system is based on software system for computer control of mac is a free software released under the terms o overall dimensions and estimated accuracy of robots, hexapods, etc. EMC2 was initially created by the IST (National Institute of Standards and Technology) and PC Linux platform with real-time extension and EMC2 hine tools, (General Public License) [7, 8]. Based on Eqs. (9)-(14), kinematics module is programmed in C language and is integrated in EMC2 software system. According to the f the GPL developed desktop milling machine prototype, basic calibration is performed on machining center during the process. assembly The analysis evidenced t hat scale factor 5 compared to the first experimental industrial-size milling machine prototype from Fig. 5 would be an optimal solution because the machine would be desktop and would have five times smaller overall sizes and overall sizes, retaining all used. Those dimensions a existing low-cost componen’ five times smaller workspace advantages of the mechanism so provide for applying the ts as well as building of other components in our laboratory.
