CNC-ACADEMY.COM TIPS: What is the CNC Control and it's Purpose...

The CNC control will interpret a CNC program and activate
the series of commands in sequential order. As it reads the
program, the CNC control will activate the appropriate
machine functions, cause axis motion, and in general,
follow the instructions given in the program.

Along with interpreting the CNC program, the CNC control
has several other purposes. All current model CNC controls
allow programs to be modified (edited) if mistakes are
found. The CNC control allows special verification
functions (like dry run) to confirm the correctness of the
CNC program.

The CNC control allows certain important operator inputs to
be specified separate from the program, like tool length
values. In general, the CNC control allows all functions of
the machine to be manipulated.

Software optimises profile cutting

Esab Automation's new powerful offline drawing, editing and nesting software for CNC profiling machines is ideal for all sizes of fabricators.

Esab Automation's new powerful offline drawing, editing and nesting software for CNC profiling machines is ideal for all sizes of fabricators. It allows drawing, nesting and cutting operations to be performed quickly offline, without fuss. Interactive nesting for improved plate utilisation is offered together with cutter path definition, marking tool definition and post processing for all CNC controls.
Using this software, the operator can develop just about anything for plate and sheet fabrication including 2D and 3D DXF and marking, forming and costing details.
The software also offers a range of productivity options.
The profile quoter defines shape, specifies plate/process details, nests and calculates the cost.
The scanned outline facility converts scanned images into vectored outlines ready to cut.
It supports BMP, TIF and other formats and can output DXF and CAM files.
The font generator turns windows text into NC code, whilst the 3D development option ensures fast and simple plate development.
Other options include a remnant plate tracer which is a unique graphic remnant tracing software.
It is very simple to operate either stand-alone or as part of an integrated system.
The automatic nesting feature maximises plate usage, optimises machine time and minimises programming time.

Mitsubishi's M64 The High-Performance CNC

Mitsubishi Electric Automation, Inc. raises the price/performance standard for compact CNCs with the introduction of the M64 family, boasting high-speed machining and high accuracy control modes. Four M64 configurations are available and include: the M64 (mill or lathe) with 7-axis control (up to 4 simultaneously), 2 spindles and 4 peripheral devices; and the M64A (mill or lathe) control which provides 4-axis control (up to 4 simultaneously), 1 spindle and 4 peripheral devices. Each model is also configured with either a 7.2-in. or 10.4-in. monochrome LCD panel and integral keypad. For even greater reduction in space requirements and system cost, an optional serial network allows one M64 display unit to monitor up to 4 CNCs.
To speed system throughput, the M64 family offers CNC/PLC parallel processing with an architecture that eliminates time delays when switching between CNC and PLC operations. The PLC scan time is less than 100 nanoseconds per step. One M64 CNC is capable of controlling multiple program paths simultaneously, with each operating either independently or working to synchronize a machining system. To reduce system costs, the M64 is capable of controlling two systems on either machine centers or turning centers.
The M64 family extends its capabilities and reach with remote I/O and is able to handle 256 DC inputs and 256 DC outputs, 4 analog inputs and 4 analog outputs over a distance of 150 ft. Up to 4 MR-J2-CT servos can be controlled by the M64 using miscellaneous command calls for controlling auxiliary equipment including turrets, tool magazines, index tables and other devices.
Mitsubishi builds numerous functions into its M64 CNCs to meet increasing customer demands. The M64 features synchronous axis (gantry function), which allows two servos to drive a single axis, threading and synchronous tapping (eliminating the need for a floating tap). A graphic trace-and-check function is also included. It allows operators to review a program's simulated tool path before running it and even while it is running. An editing function allows operators to edit one program while another is running. Users can also edit buffer data in a running program during a feed-hold operation or if a program error occurs.
To simplify system development and use, the M64 provides a range of canned programs for standard operations including tapping, boring, back boring, peck drilling, reverse tapping, bolt hole circle, line at angle, arc and grid. The M64 even allows users to generate up to five macro programs in M-code or G-code (up to four levels deep).
Mitsubishi's standard features in the M64 Series are designed to simplify machining operations through automated routines - including automatic tool length measurement - and tool life management. It also handles such tasks as nose radius compensation of a ball end milling tool, and automatic selection of nose radius compensation direction.
