Use of Parametric 3D Modelling - Tying Parameter Values to Spreadsheets at Designing Molds for Plastic Injection

Abstract

The current mechanical engineering is inconceivable without the implementation of CAx systems in design and manufacturing process of individual components. The automotive industry is a clear evidence of how CAx systems affect the innovation cycle of its product -a car. The innovation cycle in automotive was reduced from 8-12 years to the current 4-6 years. Even in this short interval automakers make some small design modifications called a facelift. Development in the automotive industry, therefore, is closely related to news and functionality CAx systems. CAD systems at the turn of the millennium are characterized as parametric graphic systems with a history tree of product creation. Parametric design implemented into CAD systems makes the model variable and open to rapid change management. The history tree in turn enables rapid editing and modification of forming or editing functions.

Simulation and Optimization of Saw Blade Production in Plant Simulation

“…The biggest advantage of this software is that we introduce the changes to the process after data analysis from the simulation, i.e. if the optimization has been achieved [12,13]. The working environment in Plant Simulation is in Figure 1.…”

Methodological Procedures Applied to the Manufacturing Systems Design

“…These relationships create a framework according to which various partial design methods V (S) can be integrated into the system concept and, at the same time, they uncover the areas unaccounted for, covered by intuitive procedures in designing [5,9].…”

An Algorithm in the Process of Planning of Safety Pathway – a Collision-Free Pathway of a Robot

“…We place the obstacle in the workspace so that a collision may occur. One obstacle is enough to approach the collision problem in the robot workspace, on the basis of which an example of the collision situation of the robot in the CATIA system and the subsequent creation of an algorithm for setting the collision-free pathway for the SCARA robot, also in the CATIA system will be demonstrated [6,8].…”

“…In order to calculate the inverse solution, it is necessary to obtain the individual articulated variables of the robot at the specified position of the end effector orientation. Therefore, we used the following formulas to calculate the sum and difference of the two angles of trigonometric functions: sin (α ± β)= sin α cos β ± cos α sin β (7) cos (α ± β)= cos α cos β ± sin α sin β (8) On the basis of the resulting matrix pertaining to the position and orientation of the robot effector Te, the following formulae apply to determine the position:…”
