Analysis of surface quality during milling with industrial robots as a function of milling spindle orientation

open access: yesProceedings of the Conference on Production Systems and Logistics, 2021
The range of tasks performed by industrial robots has become increasingly comprehensive in recent decades. This includes pick-and-place tasks with low to medium handling weights, as well as material processing tasks with medium to high processing forces.

Analysis of pin milling of pharmaceutical materials [PDF]

open access: yesInternational Journal of Pharmaceutics, 2018
Milling is an important process for tailoring the particle size distribution for enhanced dissolution, content uniformity, tableting, etc., specially for active pharmaceutical ingredients and excipient in pharmaceutical industries. Milling performance of particulate solids depends on the equipment operating conditions (geometry, process conditions and ...

Bronze Age of Direct Mechanocatalysis: How Alloyed Milling Materials Advance Coupling in Ball Mills [PDF]

open access: yesAdvanced Energy and Sustainability Research, 2021
The copper‐catalyzed Glaser coupling is conducted mechanochemically, with the milling balls and vessels being the catalyst. Thus, neither catalyst powders nor soluble catalyst salts are required. Substituting Cu0 milling tools by copper alloys not only increases the yield of the reaction, but also greatly reduces abrasion, and in turn increases ...

Compliance error compensation in robotic-based milling [PDF]

open access: yes, 2014
The paper deals with the problem of compliance errors compensation in robotic-based milling. Contrary to previous works that assume that the forces/torques generated by the manufacturing process are constant, the interaction between the milling tool and ...
