Laser cutting - Wikipedia

The process consists of preheating the metal to be cut to its ignition (oxidation) temperature, i.e., above 870°C in case of steel. The preheating is done by oxy-acetylene gas flame, which is supplied from surrounding openings of the cutting torch. When this temperature is attained, a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal.

Surface Machining - Engineering

Machining properties of wood: tool wear, cutting force and tensioning of blades i ABSTRACT Cutting processes, in general, and wood cutting processes, in particular, are complex to explain and describe with many influencing factors. Wood, in contrast to man-made fabricated materials, is not a homogenous and distinct material, but a multifaceted and

How is oxygen used in the flame cutting process?

1.3.2 Active gas melt-shearing. Active gas melt shearing cutting process (or sometimes referred to as a gas cutting) involves melting of the base material, which is then ejected using a high-pressure active assist gas. In this case, additional process energy may be generated through an exothermic chemical reaction.

Machining - Material removal processes

Laser Cutting. Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area. A co-axial gas jet is used to eject the molten material and create a kerf. A continuous cut is produced by moving the laser beam or workpiece under CNC control.

Nov 05, 2010 · 468. Just use carbide and choke up on the reamer a little. You dont need to go crazy trying to make a good part from a plasma cut piece you just need the right tools. 7/8" holes to 1" means you are definately cutting away hardened steel. Run your tools like your cutting hardened steel near the edges and youll be fine.

What kind of saw is used for gas cutting?

– When cutting half the cutter diameter or less, you should definitely climb mill (assuming your machine has low or no backlash and it is safe to do so!). – Up to 3/4 of the cutter diameter, it doesn’t matter which way you cut. – When cutting from 3/4 to 1x the cutter diameter, you should prefer conventional milling.
