Novel evaluation method for motion trajectory of machine tool feed drives based on human visual sensitivity

Prof. Ryuta Sato
Designated Professor, Nagoya University (Japan)

Machined surface quality is typically evaluated based on their visibility through human eyes, especially in dies and molds, and designed surfaces such as smart phone cases. Visible glitches are frequently observed on the surface due to imperfection of motion trajectory of machine tool feed drives. Regarding the problem, it is empirically known that the visibility of the glitches is not directly related with size of the errors. This study proposes a novel motion trajectory evaluation method based on human visual sensitivity related with surface quality. The human visual sensitivity is investigate based on the reflectance model and the visible limit of the geometrical property is formulated. Motion trajectories are evaluated based on the investigated visual sensitivity to demonstrate validity of the proposed method.

Director, HEIDENHAIN Korea Ltd. (Korea)
E-mail : ahn.dong@heidenhain.co.kr

In the office, the Digital Twin allows you to leverage the actual kinematics, parameters, and functions of your machine during part design, program creation, and simulation. On the shop floor, you benefit from reduced setup and simulation times, less program debugging, greater process reliability, and higher productivity. Beyond assisting in the creation of a verified NC program, the Digital Twin also provides support for quoting, job planning, and expert-level TNC training.

Biography
Mr. Dongyul Ahn joined Heidenhain Korea Ltd in 2006. He started as a technical engineer and participated in 5-axis projects for almost all major Korean machine tool manufacturers. Since 2014, he has been the Director of CNC Sales & Marketing at Heidenhain Korea. His company opened an Application Center in 2015 to support high-end manufacturing technology. He works together with expert engineers, and they have extensive experience from the actual working field. Digital twin is a hot topic in the market now, and Heidenhain offers optimized solutions for the actual manufacturing process.

Additive Manufacturing as the enabler of digital transformation in sustainable production

Mr. Brian Moon
Country Manager, Stratasys Korea (Korea)
E-mail : Brian.Moon@stratasys.com

Nowadays, manufacturers encounter many challenges like enhancing OEE (Overall Equipment Efficiency), responding supply chain issues, rising cost of energy, geospatial risk and ESG related regulations/requirements.
To overcome these challenges, manufacturers take a journey of digital transformation. However, digital transformation in production side (especially, factory floor) is still focusing on IT/OT integration by adding sensors to old machines or adopting new IoT ready subtractive manufacturing equipment. Additive Manufacturing can be the enabler of digital transformation in production, which provide sustainability to a factory floor.
In this presentation, I will introduce the latest status of Additive Manufacturing, its sustainability and near future outlook on autonomous digital manufacturing.

AI-based autonomous Factory solutions & Use Case

Mr. Jason Park (Jung Yoon Park)
President and CEO, INTERX Co., Ltd. (Korea)
E-mail : jason.park@interxlab.com

An intelligent autonomous factory controls the main facilities of the process to optimize real-time production plants and minimize the occurrence of problems by utilizing digital technologies such as automated production facilities, manufacturing AI, and digital twin technologies for unmanned or minimal people. Autonomous factories advance factory facilities and manufacturing systems that produce products by themselves by intelligent systems.

Using various AI models and digital twin technologies for autonomous factories, it optimizes the operation of production facilities for each process and predicts quality problems in advance to prevent defects. Produced products autonomously judge the quality of the final product using inspection AI and, when quality problems arise, deliver them to AI to optimize production conditions in the production process to help prevent problems.
As a representative example, we present a case of building a plastic injection product plant and a CNC precision processing plant as autonomous factories.
