2016-7-8  2.2. Ion Milling: Etch the Unsuitable Coating Completely from the Optic Surface with Ion Milling, and then Recoat the Optic. Ion milling is a physical etching process that involves the ionization of a gas (or combination of gases) that is accelerated by an ion source. 3 The ion source is typically directed at the surface to be etched, and the bombardment of the ions against the surface removes

Real-time thickness compensation in mirror milling

2019-9-1  The mirror milling system (MMS) is equipped with two mirror-symmetrically arranged heads, as shown in Fig. 1. The milling head, which carries the cutter, performs machining against the first surface of the part, while the support head supports the second surface of the part.

Review on support technology for mirror milling of

2021-3-24  Abstract: As a new technology for aircraft skin processing, mirror milling is an efficient and green processing technology, and has been gradually replacing chemical milling. The support technology is a key technology for mirror milling, important for size precision and surface quality of the skin, and directly affects the appearance of the outer surface of the skin.

Repair of a mirror coating on a large optic for high

The mirror coatings to be repaired were quarter wave stacks of HfO 2 and SiO 2 layers for high reflection at 1054 nm at 45° incidence in P-polarization. One of the coating layers was purposely deposited incorrectly as Hf metal instead of HfO<SUB>2</SUB> to evaluate the ability of each repair method to restore the coating's high laser-induced

Analytical prediction of temperature in laser-assisted

2018-10-29  An analytical predictive model for temperature in laser-assisted milling considering both laser preheating temperature and machining induced temperature rise is proposed. The preheating temperature at top surface is predicted first by considering the heat generation from laser and convection. The heat generation rate is described by Gaussian equation.

With this laser system, we can drill or cut holes through any thickness. It does not matter whether the glass is paper-thin and only 0.5 millimeters thick or if it is a glass block of 100 or more millimeters: The cutting kerf of the cericut is only 100 micrometres wide and thus makes it possible for us to work extremely accurate.
