This doesn't apply to your formatting question, however,
Last I knew, the # sign is used to start a comment , everything to the right of # is ignored.
If you need to output a # to your NC program you need to code it as its ascii value or 35.
example: G90G#110 could be coded in the post as "G90G", 35, "110"
Have the post alter the variable 'speed' so a spindle speed not ending in zero won't happen, such as:
change the least significant digit to zero.
speed = (int(speed/10)) * 10
or
define a new variable, say, alt_speed then a new postblock:
pfixspeed # spindle speed to end in zero
alt_speed = (int(speed/10)) * 10
speed = alt_speed
*speed
or
pfixspeed # spindle speed to end in zero
alt_speed = (int(speed/10)) * 10
*alt_speed
then substitute pfixspeed where speed is output
Here is how I solved it for our HCN4000.
define your own variable and format it: --> fmt "F" 13 thdlead
Create a routine to convert ipm to ipr:
p_whichfeed # ipm to ipr for tap cycle
if drillcyc$ = 3,
[
thdlead = 1 / n_tap_thds$
thdlead
]
else,
[
*fr$
]
find where the F7.6923 is being output from , (perhaps ptap$ ?)
if so,
Substitute 'p_whichfeed' for '*pitch' in ptap$
We purchased a new Haas ST20Y last fall for our up and coming in-house education center.
We noticed that the spindle made a high pitch whine that became intolerable at spindle speeds above 3K.
The installation tech said that that was normal for this machine since Haas changed the design of the spindle to a belt type and all the new ST20's have the same noise.
We measured the decibel levels at 1K, 2K, 3K, 4K, and 5K .
We found that at 1K the level was 76.6 and that the level would consistently increase to 105.0 at 4500 rpm.
I am hard pressed to believe that this situation should be considered "normal" as the noise can make you feel ill.
Ted Nugent wasn't as loud !! (or The Who, or Blue Cheer)
Does anyone else out there have the same problem or am I just whining as bad as the spindle ??
