- G-code programming
Programs written to operate NC machines with control systems that comply with the ANSI/EIA RS-274-D-1980 Standard. A program consists of a series of data blocks, each of which is treated as a unit by the controller and contains enough information for a complete command to be carried out by the machine.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- numerical control ( NC)
numerical control ( NC)
Any controlled equipment that allows an operator to program its movement by entering a series of coded numbers and symbols. See CNC, computer numerical control; DNC, direct numerical control.
- waterjet cutting
Fine, high-pressure (up to 50,000 psi or greater), high-velocity jet of water directed by a small nozzle to cut material. Velocity of the stream can exceed twice the speed of sound. Nozzle opening ranges from between 0.004" to 0.016" (0.l0mm to 0.41mm), producing a very narrow kerf. See AWJ, abrasive waterjet.
Siemens' new Sinumerik MC controller is a universal, open, industrial PC-based CNC system. Its optimized motion control, high-performance automation and integrated Windows 10 operating system make it a suitable control for fabrication and specialty machines, including woodworking, stone-cutting, laser and even conventional basic grinding machines. With an open operating concept, this new control system is also suitable for certain additive manufacturing, metal forming, adhesive applications, plate cutting, grinding and laser or waterjet cutting.
The Windows 10 operating system provides easy integration of customized software for these machines. The open operating concept and the extensive range of interfaces make it a universal, open control, which can be easily utilized in existing fabrication machine solutions. Sinumerik Motion Control (MC) is optimally equipped with the latest generation of the proven Sinumerik numerical control (NC) kernel to meet the demands of the fabrication industry.
It facilitates motion control with enhanced accuracy and — thanks to G-code programming — offers the freedom and flexibility in machine control. The integrated Simatic S7-1500F PLC increases the speed of response which, in turn, improves the automation performance. Sinumerik MC offers Safety Integrated as the Siemens industry standard for safety and implements the multiple-layer Defense-in-Depth-Concept for IT security.
Sinumerik MC can be engineered in the Totally Integrated Automation (TIA) Portal, which provides a highly efficient engineering environment. This opens up new engineering opportunities for machine builders. Conventional PLC languages and high-level language programming are available in the TIA Portal to create automation programs for the control system. This is assisted by fast and simple commissioning offered by Sinumerik Operate, the graphical user interface of the Siemens CNC system.
Sinumerik MC is a suitable controller for fabrication machines that require an individual user interface and powerful motion control.
