The invention relates to a method of forming a void with a circular cross section in a substrate, more particularly to forming through holes electronic substrates The method comprising the steps of causing a laser cutter to traverse in an arc to an intended circumference of the void, traversing the intended circumference of the void at least once, wherein the lead in from the arc to the circumference comprises a radius.

Laser systems and methods insert a settling time before and after each tooling action. A peak AOD excursion generally occurs at the transition in velocity between inter-feature moves and tooling moves. This transition occurs both before tooling (on the approach to the tooling location) and after tooling (on the departure from the completed tooling location to the next location). By adding a settling delay on each end of the tooling period, the AOD excursion is allowed to settle to a lower value. This then allows higher inter-tooling velocities (for high throughput) while keeping the AOD travel excursion within the bounds of the system's AOD configuration.

The present disclosure is directed toward a machine tool configured to perform small-scale, high-accuracy drilling operations for small-hole applications. The small-hole applications for which the machine tool is designed includes holes with one or more diameters. A part may have a larger-diameter hole that penetrates through a fraction of the thickness of a part and a smaller-diameter hole that penetrates from the bottom of the larger-diameter hole through the remainder of the part thickness. Additionally, the machine tool may be used with parts in any of the following categories: (i) both the step-hole and the flow-hole are created using the machine tool; or, (ii) the step-hole is created with an up-stream process and the machine tool may accept the part, measure the step-holes and create the flow-holes; or, (iii) no step-hole is used and the machine tool may accept the part, measure the raw surface and create the flow-holes.

A substrate having one or more shaped effusion cooling holes formed therein. Each shaped cooling hole has a bore angled relative to an exit surface of the combustor liner. One end of the bore is an inlet formed in an inlet surface of the combustor liner. The other end of the bore is an outlet formed in the exit surface of the combustor liner. The outlet has a shaped portion that expands in only one dimension. Also methods for making the shaped cooling holes.

A method of combined laser and oxy-cutting, including heating an area of the material to be cut to an enabling temperature range with a laser beam and introducing an oxygen stream into the heated area, thus cutting the material. Wherein the laser beam is directed in a periodic path.

Methods and systems for laser cutting of components are disclosed herein. Examples are specifically suited for laser cutting relatively large components of e.g. a vehicle framework such as a unitary side panel of a vehicle door. Multiple robots may perform laser cutting operations substantially simultaneously.
