CNC Panels Promote Clear, Efficient Operation
Eastec 2017: Siemens will present its Sinumerik 15" and 19" blackline panels for its Sinumerik 840D sl control system.
Siemens will present its Sinumerik 15" and 19" blackline panels for its Sinumerik 840D sl control system. The 15" panel features an alphanumeric keypad on the right that can be operated via touch control, while the 19" display can show all entries made in widescreen format. This configuration promotes clarity and efficient operation becasue the superimposed keypad doesn’t restrict the 15” display during data entry, the company says. Meanwhile, touch technology enables rapid interaction with the graphical user interface, even when the machine operator is wearing gloves.
Both panels have an integrated glass panel on the front side and are designed with IP66 (15") and IP65 (19") degrees of protection. They are resistant to liquids and dust and can be operated under harsh industrial conditions. An integrated key-lock helps safeguard against operating errors. The operator panel can provide a basic machine display, with three or four channels showing as many as 13 axes. Sinumerik blackline panels also feature durable LED background lighting that provides 40 percent energy-savings compared to conventional neon lamps, the company says.
Combined with the Sinumerik 840 D sl CNC in in mid-range and high-end milling, turning, grinding and laser cutting machines, the blackline panels can be used as an operating and programming station. This is the case not just for job shop production, but also aerospace composite machining, power generation and medical part manufacturing, as well as toolmaking, moldmaking and rotary indexing applications.
It is common to machine several identical workpiece attributes from within a single program. Consider the four identical circular counter-bored holes that must be milled in the workpiece shown in Figure 1.
Though applied for different reasons on different machine types, all forms of compensation allow the CNC user to allow for unpredictable conditions related to tooling.
Properly evaluating machine tool capability requires understanding how the both user and the builder can influence precision.
