Positioning accuracy in machine development
Simulation of machines and systems in motion using Ansys Mechanical
In this training, you will learn how to increase the accuracy of machines by simulating static, dynamic, and thermal environmental influences as early as the development stage. This training is offered as a 2-day course.
Duration
2 days
Prerequisites
Basic knowledge of Ansys Mechanical
Software used
Ansys Mechanical
- Answer practically relevant questions about the machine tool development with FEM
- Achieve better workpiece quality and higher productivity
- Targeted practice of relevant analysis types in workshops
- Examine influence parameters on the Tool Center Point (TCP)
Description
Many leading machinery manufacturers use modern development tools and methods to develop better machines more quickly. As a central component of that effort, the use of FEM software has become an inextricable part of the virtual product development process for machine tools. It enables comprehensive static, dynamic, and thermal analyses of digital prototypes and thereby efficiently answers many questions without the costly and time-consuming construction of real prototypes.
This training provides developers and designers with the necessary knowledge for the numerical simulation of machine tools. You will learn how to use FEM analyses to answer many practical development questions concerning machines and systems in motion in such a way that the machine becomes more productive and cost-effective, and a better product quality is achieved. In various workshops, we develop the targeted handling of different types of analysis.
The course is beneficial to anyone looking to make predictive statements on possible design variants at an early concept phase or those who want to use analysis technology to specifically address troubleshooting in the event a problem arises during operation.
Detailed agenda for this 2-day training
Day 1
01 Machine oriented FE modeling
- Model preparation (geometry, contacts, material, meshing)
- Workshop: defining connecting elements (linear guides)
- Workshop: defining a ball screw
02 Effect of moving loads on the straightness of the TCP
- How does the TCP (tool center point) shift relative to the WPP (workpiece point) due to the influence of gravity when the tower moves?
- Workshop: defining joints to automate the tower movement relative to the machine bed and evaluating the relative displacement
03 Static stiffness in the uncontrolled state
- Creating the relevance matrix for the unregulated state
- How great is an axis’ influence on the TCP’s compliance?
- Do the axes influence one another?
- Workshop: creating and evaluating the relevance matrix
- Which machine components have the largest deformation components?
- Workshop: evaluating the deformation components at component level
04 Static stiffness in the controlled state
- Investigating the behavior for the controlled state
- Workshop: how does an ideally stiff controller behave and how does this affect the TCP’s displacement?
- Position control via direct or indirect position measuring systems
- Mounting location for the direct position measuring system
- Workshop: how does the direct position measuring system’s mounting location affect the static rigidity?
Day 2
05 Dynamic accuracy of the feed axes I
- Determining critical frequencies and eigenmodes by modal analysis
- Workshop: determining eigenfrequencies and eigenmodes
- Workshop: displacement of eigenfrequencies due to design changes
06 Dynamic accuracy of the feed axes II
- Calculating the TCP compliance using the frequency
- Workshop: transfer function between the drive and measuring system as well as the drive and TCP
07 Accuracy-relevant, stationary thermal growth
- Temperature field analysis with realistic boundary conditions
- Coupling between thermal and mechanical analysis
- Workshop: determining the thermally induced displacement of the TCP
08 Advanced analyses
