Precise, easy to use, fast to setup and program. Traditional waterjets have been used for applications such as cutting diapers, but nobody made a machine tool for the machine tool market. The abrasivejets that were available for machine tool work were very low tolerance, and built from a variety of custom configurations. OMAX brought precision, ease of use, and a standard product line to the market.

FIXTURES: There are many methods of fixturing the material down. The simplest is to place a plate of material on the machine, and anchor it with weights. Handi-grips are also used to secure the plate in the X and Y directions. More advanced fixturing can be employed if needed for specialty applications or secondary machining. waterjet brick

MATERIALS CUT:
Dual pressure piercing allows for piercing of glass with minimal risk of cracking. OMAX JetMachining Centers come standard with dual pressure capabilities. OMAX Machines also have a special “brittle mode” that works in conjunction with low-pressure piercing to slowly raise the pump pressure during the pierce to avoid a sudden shock to the material by a rapid change in pressure. Using these techniques reduces the risk of cracking, making glass cutting into a very profitable venture.

MOLD MAKING
Draft – When making a pattern it is best to taper the edges so that the pattern can be removed without breaking the mold. This is called draft.
Undercut – The opposite of draft is an undercut where there is part of the pattern under the sand making it impossible to remove the pattern without damaging the mould

The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners. TIME OF FLIGHT Time of flight (TOF) describes a variety of methods that measure the time that it takes for an object, particle or acoustic, electromagnetic or other wave to travel a distance through a medium. This measurement can be used for a time standard (such as an atomic fountain), as a way to measure velocity or path length through a given medium, or as a way to learn about the particle or medium (such as composition or flow rate). The traveling object may be detected directly (e.g., ion detector in mass spectrometry) or indirectly (e.g., light scattered from an object in laser doppler velocimetry). LIDAR LIDAR (Light Detection And Ranging) is an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. CONFOCAL Confocal laser scanning microscopy TOMOGRAPHY skyscan Tomography is imaging by sections or sectioning, through the use of wave of energy.[1] A device used in tomography is called a tomograph, while the image produced is a tomogram. The method is used in radiology, archaeology, biology, geophysics, oceanography, materials science, astrophysics and other sciences. In most cases it is based on the mathematical procedure called tomographic reconstruction. The word was derived from the Greek word tomos which means "a section", "a slice" or "a cutting". A tomography of several sections of the body is known as a polytomography.
