Prediction of contour accuracy in the end milling of pockets

Journal of Materials Processing Technology, 2001
Abstract Many die and mold parts surface contours are produced by end milling operations. The contour accuracy of the milled pockets is strongly influenced by the cutting tool deflection caused by the cutting forces. For milling a complex shape or a simple rectangular pocket, the accuracy of contours in corner cutting is mainly influenced by the ...

Backup roll contour of a SmartCrown tandem cold rolling mill

Journal of University of Science and Technology Beijing, Mineral, Metallurgy, Material, 2008
Abstract SmartCrown was a new system developed by VAI for improving the strip profile and flatness control first applied in 1700 mm tandem cold rolling mills at Wuhan Iron & Steel (Group) Corporation (WISCO). After tracing and testing, the application of the conventional crown backup roll matching the SmartCrown work roll of the production mill led ...

Advanced Design of Work Roll Contours for Different Roll Mill Types

2021
Steel producers are competing to roll non-grain oriented silicon (NGOS) strip with 1.25 m in width, 0.5–0.35 mm in thickness, and a profile deviation that is less than 5 micron-meters. Mathematical Models are indispensable tools to study the mechanism of work roll contours during rolling, but they require industrial tryouts to validate their effects on

Targeted Silicon Ultra-Thinning by Contour Milling for Advanced Fault Isolation

International Symposium for Testing and Failure Analysis, 2019
Abstract In this paper, we present methods for targeted silicon thinning by contour milling to overcome challenges associated with thinning large devices to under 5 µm remaining silicon thickness. Implementation of these techniques are expected to improve the yield of ultra-thin sample preparation and thermal stability of the device ...

ACCURACY CONTROL DURING MILLING OF CONTOURS ON CNC MACHINES

International Scientific and Technical conference "The Progressive Technics, Technology and Engineering Education", 2018
У роботі розглянуто функціональні можливості сучасних обробних центрів із ЧПК, що дозволяють виконувати обробку всієї деталі, навіть такої складної, як турбінна лопатка, за одну операцію. Визначено також, що при обробці поверхонь складної форми умови різання істотно змінюються уздовж формотворною траєкторії. Це призводить до появи помилки, природа якої

Tool path generation for contour parallel milling with incomplete mesh model

The International Journal of Advanced Manufacturing Technology, 2008
In this paper, a tool path generation method for contour parallel milling based on an incomplete two-manifold mesh model, namely, an inexact polyhedron which is widely used in recent commercialized computer-aided manufacturing software systems is presented. The method consists of three major steps: machining area detection, 2D offset, and path linking.

Modelling the Work Roll Wear Contour in a Four‐high Mill

steel research international, 2007
A method for modelling the wear contour work rolls in a four‐high mill has been developed. The modelling is build up with statistical methods. The bases for the statistics are simulations of different rolling cases and measurements from the production of heavy plates in Oxelösund. These calibrations gave a well‐working model.
