A common type of fixture, used in materials tensile testing (Grip-Engineering). A fixture is a work-holding or support device used in the manufacturing industry. [1] [2] Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchangeability.
Descriptive data (geometrical value) vary depending on the type of tool. The data fields are specified in the class list of characteristics. The meaning of the geometrical data fields is illustrated in diagrams and pictures. DIN 4000 recommends diagrams and pictures for their explanation.
The table shown is a manually operated type. Powered tables under the control of CNC machines are now available, and provide a fourth axis to CNC milling machines.Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture.

The fundamental basis for creating the cutter paths suitable for CNC milling are functions that can find valid cutter locations, and stringing them together in a series. There are two broad and conflicting approaches to the problem of generating valid cutter locations, given a CAD model and a tool definition: calculation by offsets, and ...
CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
STEP-NC interface on a CNC, showing product shape and color-coded tolerance state. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, [1] adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.
LinuxCNC is a software system for numerical control of machines such as milling machines, lathes, plasma cutters, routers, cutting machines, robots and hexapods.It can control up to 9 axes or joints of a CNC machine using G-code (RS-274NGC) as input.
