ABOUT IMPACT

IMPACT is a high-speed all-digital machine vision micro-system that setsnew industry standards for inspection power and flexibility. IMPACT is

unsurpassed in the industry, achieving a breadth of application andprice/performance ratio unavailable in low-end vision sensors or smartcameras. IMPACT achieves an unparalleled combination of ease-of-usefor straightforward applications, and power and flexibility for advancedapplications through the use of PPT VISION's all-new Inspection Buildergraphical user interface software. In addition, its advanced Ethernet andInternet capabilities make IMPACT the perfect tool for remote monitoringand control as part of a network with multiple inspection points. Thiscombination of power and flexibility allows IMPACT to be easily

programmed by end users and also easily customized by OEMs andsystem integrators.

BACKGROUND OF THE INVENTION

Impact machines for working by the employment of high kinetic energy are

machines for working in the first place metal, such as cutting, punching,

and plastic forming of powder components, powder compaction, and similar

operations, in which the velocity of a ram, which may consist of a hydraulic

piston, may be essentially higher than in conventional presses. Also

polymeric and ceramic working materials can be conceived, as well as

various composites of metals, polymers and ceramic materials. The

working principle is based on the development of a very high kinetic energy

of short duration instead of a high static press force of long duration.

Impact machines are well suited for the manufacture of annular articles,

such as gears, bushings, and the like, in a closed mould cavity. However, it

is a problem to get the formed body out of the mould cavity withoutdamaging it. This particularly is true for articles which are formed of metal

powder and which have not been consolidated through coalescence of the

powder, i.e. welding of the powder grains, to form a well united, strong

body. Therefore, it is a particularly great risk for damages when articles are

manufactured, which are formed of powder, but also articles which are

formed of a solid blank can crack or form layers, when they are pushed out

of the mould cavity. Besides, it has not been possible to perform the

manufacture in a rational mode according to prior art, i.e. in a mode which

provides the high production capacity which is required in the first place for

the manufacture of mass products, such as gears, bushings, and the like.For example it is a problem to remove the mandrel out of the formed article

by known technique.
