How do you solve 4x plus y70?
If you mean: 4x+y = 70 then y = -4x+70 whereas -4 is the slope of the line and 70 is the y intercept
What is incremental positioning in cnc machining?
A machine can measure either from the zero point, or from the last position that was. For example, when you say "X10", you mean 10mm from the zero point of the axis X, or you may mean 10mm further than the last position the machine was on the X axis. The way of measuring is decided from the G codes G90 and G91. Running the G90 command, the machine will start to measure using absolute coordinates (measuring from the zero point of the axis) and running the G91 command will set the machine into "incremental measuring". For making matters more clear, see the following two examples. They generate both exactly the same thing, a rectangle as shown in file p7.jpg. The first code example uses absolute measurements and the second uses incremental measurements. At this point it should be said that almost all machines measures by default using G90 (absolute coordinates). For the following example, we suppose that somehow, the machines start from point 10,10 and not 0,0 REM --- a rectangle drawn using absolute coordinates --- G90 ; Set absolute measurement G1 Y80 G1 X80 G1 Y10 G1 X10 REM --- a rectangle drawn using incremental coordinates --- G91 ;Set incremental measurement G1 Y70 G1 X70 G1 Y-70 G1 X-70
How can you tell between a fake and real white five pound note?
A real $20 bill will feature a portrait watermark. You can see it by holding the note to the light to see a faint image of Andrew Jackson in the blank space to the right of the center portrait. The watermark should be visible on both sides of the bill. ☜(ﾟヮﾟ☜)
