Constant lead Threading (G32) Interpolation Funtion

Tapered screws and scroll threads in addition to equal lead straight threads can be cut by using a G32 command.
The spindle speed is read from the position coder on the spindle in real time and converted to a cutting feedrate for feed-per minute mode, which is used to move the tool.


Example of threading
FORMAT

In general, threading is repeated along the same tool path in rough cutting through finish cutting for a screw. Since threading starts when the position coder mounted on the spindle outputs a one-spindle-rotation signal, threading is started at a fixed point and the tool path on the workpiece is unchanged for repeated threading. Note that the spindle speed must remain constant from rough cutting through finish cutting. If not, incorrect thread lead will occur.

LZ and LX of a tapered thread

In general, the lag of the servo system, etc. will produce somewhat incorrect leads at the starting and ending points of a thread cut. To compensate for this, a threading length somewhat longer than required should be specified.

Ranges of lead sizes that can be specified
Metric input = Least command increment 0.0001 to 500.0000 mm
Inch input = Least command increment 0.000001 to 9.999999 inch


Example


" WARNING "
1. Feedrate override is effective (fixed at 100%) during threading.
2. It is very dangerous to stop feeding the thread cutter without stopping the spindle.
This will suddenly increase the cutting depth. Thus, the feed hold function is
ineffective while threading. If the feed hold button is pressed during threading, the tool will stop after a block not specifying threading is executed as if the SINGLE BLOCK button were pushed. However, the feed hold lamp (SPL lamp) lights when
the FEED HOLD button on the machine control panel is pushed. Then, when the tool stops, the lamp is turned off (Single Block stop status).
3. When the FEED HOLD button is pressed again in the first block after threading mode that does not specify threading (or the button has been held down), the tool stops immediately at the block that does not specify threading.
4. When threading is executed in the single block status, the tool stops after execution of the first block not specifying threading.
5 When the mode was changed from automatic operation to manual operation during threading, the tool stops at the first block not specifying threading as when the feed hold button is pushed as mentioned in Warning 3.
However, when the mode is changed from one automatic operation mode to another, the tool stops after execution of the block not specifying threading as for the single block mode in Note 4.
6. When the previous block was a threading block, cutting will start immediately without waiting for detection of the one-spindle-rotation signal even if the present block is a threading block.
G32Z _ F_ ;
Z _; (A 1-turn signal is not detected before this block.)
G32 ; (Regarded as threading block.)
Z_ F_ ; (One turn signal is also not detected.)
7. Because the constant surface speed control is effective during scroll thread or tapered screw cutting and the spindle speed changes, the correct thread lead may not be cut. Therefore, do not use the constant surface speed control during threading. Instead, use G97.
8. A movement block preceding the threading block must not specify chamfering or corner R.
9. A threading block must not specifying chamfering or corner R.
10. The spindle speed override function is disabled during threading. The spindle speed is fixed at 100%.
11. Thread cycle retract function is ineffective to G32.

CNC Programming Circular Interpolation

Definisi G02, G03, I, J & K
  • G02: Circular interpolation (CW)
  • G03: Circular interpolation (CCW)
  • I, J & K (Use when <=360 degree) " Incremental distance from SP to CP of arc "
  • I: Specifies the incremental ±X distance from the center of the tool at the start of the arc to the center of the arc.
  • J: Specifies the incremental ±Y distance from the center of tool at the start of the arc to the center of the arc

Circular interpolation
why R?

•R is easier to define, easier to make a mistake and get an incorrect radius.
•With R, the machine still do the work whether the R is correct or incorrect.
•With incorrect I, J & K, the machine will stop and gives an error message before executing.
•With R, to generate a circle path of over 180 degrees, then specify a negative R.

Avoid the mistakes by applying CNC code transmission machine controller

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

  •  RS-232 -
Recommended Standard 232 (RS-232) is a standard for serial communications connecting between a
PC and a CNC controller.
  • Port-
Serial communications port on PC. A 'port' serves as an interface between the computer and the CNC
controller.
  • Baud -
A unit used to measure the speed of signaling or data transfer, equal to the number of pulses or bits per
second: baud rate.
  • Parity-
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.
  • Data-
The Data rate is the number of bits that are conveyed or processed per unit of time.
  • Stop-
The "stop bit" is actually a "stop period" in the transmission of information to the CNC controller.
  • Flow-
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.
  1. 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".
  1. 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".
  • Timeout-
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.
  • DNC -
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

Learn how to run the machine by CNC machine programming

Running CNC machine, there are some CNC machine programming should be operated by operator for making sure that everything works well by the time it’s used for working. In general, at least two kinds of axes program, as followed the linear which produce straight stripe while the rotary that’s more rounded. Though they’re all dealt with the operator, the loading of working process is done automatically. Once the machine has greater axes, it’s subsequently called complex machine. Before it’s used for manufacturing, the motion that’s fitted in the machine should be controlled well so it’s able to be run the process of cutting the items.

The CNC machine programming can be successfully regarded once it’s able to replace the working process more than two axes. Instead of that occasion, you need to ask the operator just in case there’s something troubles with the machine. To enhance the performance of the CNC program, there are several items such as Automatic tool changer, Spindle speed and activation, and Coolant which those of them are having each factions while the machine’s processed.

For those who already engaged for quite some times with this machine, doing by their own isn’t big deal. However, those who haven’t yet, please contact the operator who guide you to run the machine, including the uploading the software of the CNC machine programming for better machine to produce the greatest result.

Setting up a Vise toward a CNC Milling Machine

Indicating the vise of your CNC milling machine vise is included in the most important thing of machining process. To cut the parts correctly, the fixture of work-holding is supposed to be definitely straight. Through digital indicator or a dial, you may get the vise become straight in .0001 from an inch, to result in accurate parts within the machining environment. Therefore, you need a wrench, mallet, and t-bolts. Pleas pay attention to the instructions.

First, clean the table of cnc milling machine vise of all metal chips and debris. It is essential that you clean the table and be flat. Then, use the stone of sanding to remove anykind of rust from your table and also compressed air in getting in crannies and nook to remove the debris which you cannot see through naked eyes. Next, you may place a vise to the table by the jaw plate to face to the front. The vise is supposed to be placed to make the vise C-slots are more than two T-slots corresponding toward the table. Tighten your bolts, then loosen enough to wiggle easily the vise by using one hand, then tap with a wrench or a mallet.

Next, bring in manual way the spindle toward the vice, and leave its bottom one foot from the vise. Then, attach the holder of indicator toward the spindle. You bring down the spindle so the tip would be between the two jaws vise. You move to the back the spindle to allow it pressing against the jaw at the back. Then, spin the indicator bezel to be zero. You may move  yoru spindle from the left to the right. Last, tap your jaw to get the solid zero. You may use the wrench and tighten carefully the jaw as well as re-check the axis of your cnc milling machine vise.
