• Common computer chores: number crunching, text and file processing, screen manipulation
• PLC, implemented in software, runs in the background
On The Fly (Dynamic) Z Axis Offset
The one great feature about a knee mill is the ability to crank the table up or down as desired even while cutting the part. This is now possible in the Numatix control, and can be utilized in all axes, not just in Z.
Each axis can be cranked into a new relative position even while cutting your part. The offset can be changed, by the handwheel and the jogging pushbuttons, before or while the program is running.
2 Axis Programming from CAD is Automatically Wrapped Onto a 4th Axis Cylinder
Developed especially for the roller die industry, this feature saves many hours of CAD time.
Setup Tool Length
A pop up window lets the operator enter tool length either as a number (if known) or as measured on the machine.
The operator can use or ignore tool radius (for ball nose) and enter the current Z, if not zero, which is saved for the next tool.
In addition, tool length can be incremented.
Any automatic sequence that may require operator intervention, e.g. tool changer, can be displayed in real time. The full sequence is displayed while a moving color bar highlights the current operation. If an error occurs the erroneous operation stops and blinks. The operator can go backward and forward by the arrow keys. Once the problem is solved the program can be resumed.
Your control comes complete with all the tools available to customize your screen. Many customers find it valuable to generate custom menus that prompt the operator through their part setup or to complete complex formulas based on the operator’s input.
Run Simultaneous Programs
It may be advantageous to run other programs on your control in between CNC operations. With Numatix you are able to call up a SPC (or other) program, record key information, then resume your CNC program without rebooting, re-homing, or searching for the point where you stopped in the program.
Powerful word-processor for interactive program editing:
• Up to 250 MB or 1,000,000 lines file size
• Up to 5 simultaneous open windows, with zoom
• Automatic generation of backup file
• Automatic program save before exiting the editor
• Moving and copying text inside a window or between windows
• Search, search and replace, compare two files
• Merging or splitting of programs
• Syntax check for the program; if error is detected the cursor points to the erroneous data
• Point and shoot directory and file selection
• 10 bookmarks can be set and recalled
• Undo changes to a line, undelete lines
• Print to a printer
Mid Program Restart
Your Choice! Restart from – any given line number – any given block number – a percentage of the program – or your tool’s current location. The control will read all previous commands and begin work from the point you have defined in seconds. The position and spindle are resumed simply by pressing Cycle Start and following on-screen instructions.
Fully Independent Axis Control
Some controllers require identical mechanical and electronic feed back to be present before the control will function correctly. Your Numatix control will maintain the correct, coordinated feeds and speeds regardless of mechanical axis properties. A machine that has a X axis with an odd pulley ratio and 1000 lines encoder can work with coordinated precision when tied to another axis which has a direct drive and a 5000 lines encoder. Numatix allows you to mix torque mode control on one axis and velocity mode on another. Even with a 4th axis rotating part or a 5 axis contouring move the cutter motion is based on the actual speed of the cutter tip as it travels across the part.
Jerk is the rate at which the acceleration changes. Jerk factor is the time it takes the acceleration to rise and fall, and it converts step acceleration into a trapezoidal or triangular acceleration.
Two linear jerk factors can be set up to 250 msec- one for positioning and another for interpolation.
The Jerk factor generates bell-shaped feed profile and is essential for high-speed contouring.
The Numatix control has the internal power to correct for machine out of square conditions. Some times it is impossible or very costly to correct for poor machine geometry. The Numatix control provides internal formulas to electronically correct for machine geometry error. Let’s take this one step further. Suppose the only way a part will fit onto your machine is by mounting it askew to the axis. You can now establish a new working plane which allows the use of your standard X, Y, Z, program. In this example the Numatix control will output coordinated motion when your program commands a straight line move in only one axis.
5 Axis Programming
Many 5 axis moves are really 2 or 3 axis moves in a rotated plane. With a Numatix control on your 5 axis machine tool, you can program in simple 3 axis mode after placing the control into a rotated and/or titled plane.
If security is a factor, the Numatix CNC Control Software source code can be deleted from the control (the compiled file is unreadable and useless for competitors).
For greater security, up to 9 levels of access are provided via user name and password.
Any access is logged to a file.
More Standard Features…
The spindle motor can be programmed both as an axis in degrees or as a spindle in RPM, as long as it has an encoder. This is used for some tool changers and for rigid tapping.
The mode can be switched anytime without losing position.
All kinds of tool changers can be programmed in the internal PLC.
There are four basic types of tool changer:
• The tool is picked up solely by axis motion
• The tool is taken directly from the magazine, with or without axis motion
• The tool is exchanged with a new tool from the magazine by a Tool-Changer-Arm (TCA). This is also called Random ATC because tools are not returned to the pots from which they were taken
• The TCA exchanges tools with an Intermediate Arm, which is loaded ahead of time from the magazine
For M6, T represents actual tool number. For a random ATC, the computer finds and updates the pot number in the tool table. For non-random ATC, the pot number is set to the tool number. M6 also sets the tool offset according to the entry in the tool table.
Endless Rotary Axis
When set, such an axis behaves as a linear axis for interpolation but its limits are set internally for thousands of revolutions.
Unwinding is performed automatically in the following cases:
• Jogging to zero or positioning command: The axis moves at the shortest path (180 deg or less)
• Incremental programming of zero move: There is no motion but the current position is reduced by multiples of 360 to the range +-180 deg
• Spindle operation: When the axis is used as a spindle it is constantly kept in the +-180 deg range
Any axis can be switched to Follower mode.
In this mode, the axis is moved by a feed command rather than position. A follower axis can follow feedback signal (force, position), pushbuttons, another axis, etc.
The mode can be switched anytime without losing position.
Two axes can be setup as a differential pair, using the ratio between them.
This is required for some CA heads in which the A-axis is driven through the C-axis.
Up to 2 gantry axes, each driven by 2 independent servos, are supported.
If necessary, the Reference routine can align the 2 servos to ensure squareness.
Ball and Bull Nose Cutter Radius Compensation
This compensation is used for 3D contouring. It requires a post-processor that can generate IJK vector in addition to XYZ.
It also works with 5-axis profiling.
Standard drilling cycles work with 5-axis TCP.
Rigid tapping can be used on machines with servo spindle.
Three different displays can show where the part-program is. They can be switched any time:
• Block number (N), as appears in the program
• Sequential line count, regardless of N
• Percentage of the program in 4 digits
The PLC is implemented in software and runs constantly in the background.
It is used for background operations, such as preparing the next tool, spindle control, display, alarm, watchdog, etc.
The PLC reads and writes I/O's from an I/O board with a supplied driver. The I/O ports are numbered by the retrofitter so there is no need to use absolute addresses. The PLC copies the I/O's to/from PLC designated registers. In addition, it intercepts all keyboard keys; these key-codes can be modified, used as inputs, or pass-thru.
700 registers are available for use. Of the 700 registers, 200 registers are associated with the control software variables. These 200 variables can be read and/or written, such as mode, feed, position, leadscrew compensation, trace-error, etc.
PLC programs are written and compiled using the control software editor, no additional tools are needed.
PLC registers can be displayed on the screen in real time in different formats. In addition to numerical values, they can point to text messages with variable colors.
