Can you provide a sample of the input date and explain what the output should be. In the meantime this is my guess at what you are trying to achieve.

#!perl
use strict;
my $axis;
my %output;
while (<DATA>){ 
  my ($null,$x,$y,$z,$xb,$yb,$zb,$tp,$f1,$f2) = split ',',$_;
  next unless defined($f2) ; #skip incomplete line
  
  if (($x<10) && ($y<10) && ($z<10)){ 
    $axis = 'bias';
  } # Bias
  elsif ($x>30){ 
    $axis = "x";
  } # X
  elsif ($y>30){ 
    $axis = "y";
  } # Y
  elsif ($z>30){ 
    $axis = "z";
  } # Z
  else {
    next;
  }
# Temperature
  if (($tp<45) && ($tp>35)){
    $output{$axis}{40} .= $_;
  } #-40
  elsif (($tp<25) && ($tp>15)){
    $output{$axis}{20} .= $_;
  } #+20
  elsif (($tp<85) && ($tp>75)){
    $output{$axis}{80} .= $_;
  } #+80
}

foreach my $axis (sort keys %output) {
  open my $fh, '>', $axis.'.txt';
  print "Creating $axis.txt \n";
  foreach my $temp (sort keys %{$output{$axis}}) {
    print $fh $output{$axis}{$temp};
  }
}

#$null,$x,$y,$z,$xb,$yb,$zb,$tp,$f1,$f2
