To make the machine is more effective,
CNC code transmission machine controller is highly recommended to apply. For detailed functions, this controller plays significant role in stimulating the motion of axes, including doing what has been commanded by the operator. Once it’s applied the items which useful for the working loading process work based on their each role. Through this special program as well, the mistakes which probably made by the program are able to be fixed and removed to be replaced by the new one. While in the same time, when the program is doing something right, it’s also reporting as it is.
As long as this controller’s
working well, that’s the machine can be trusted professionally. Principally, the work of
CNC code transmission machine controller is separating the buffer and motion parts which already owned by the machine. Both of them have been standardized so everything’s relied on the program that’s operated by the operator get along with its each programming’s.
The motion controller is usually placed on the users’ personal computer which’s designed by simpler way since it doesn’t require additional
software anymore. The users, even more, can apply t by using the portable device such as USB. When the machine’s provided by the controller, it results are more amazing since the users don’t have to panic for the mistake commands since it can be minimized by
CNC code transmission machine controller.
DEFINITIONS
Recommended Standard 232 (RS-232) is a standard for serial communications connecting between a
PC and a CNC controller.
Serial communications port
on PC. A 'port' serves as an interface between the computer and the CNC
controller.
A unit used to measure the speed of signaling or data transfer, equal to the number of pulses or bits per
second: baud rate.
The condition of the number of items in a set, particularly the number of bits per byte or word, being
either even or odd: used as a means for detecting certain errors.
The Data rate is the number of bits that are conveyed or processed per unit of time.
The "stop bit" is actually a "stop period" in the transmission of information to the CNC controller.
In
computer networking, flow control is the process of managing the rate of data transmission between
two nodes to prevent a fast sender from overrunning a slow
receiver.
- Hardware flow control (RTS / CTS)
Flow control can be done either by control lines in a data communication interface RTS (Request To
Send)/CTS (Clear To Send) and DSR (Data Set Ready)/DTR (Data Terminal Ready), which is usually
referred to as "hardware flow control".
- Software flow control (XON / XOFF)
Or by reserving in-band control characters to
signal flow start and stop (such as the ASCII codes for
XON/XOFF). Common
RS 232 control lines are XON/XOFF is usually referred to as "software flow
control".
A period of time after which an error condition is raised if data has not been sent or received. If the
software does not acknowledge the message within the preset timeout period, a error is assumed to
have occurred.
Direct Numerical Control, also known as Distributed Numerical Control, (both DNC) is a common
manufacturing term for networking
CNC machine tools. On some
CNC machine controllers, the
available memory is too small to contain the machining program (for example machining complex
surfaces), so in this case the program is stored in a separate computer and sent Direct to the machine,
one block at a time. While BobCAD-CAM has the
