HD58456: LACMAC : INCORRECT TOOL PATH ON PROFILE TURNING OPERATION FOR S OME ANGLE VALUES

APAR status

• Closed as documentation error.

Error description

• LacMac : Incorrect tool path on profile turning
  operation for some angle values.
  .
  SCENARIO:
  1) Open the provided CATProcess
  2) Replay tool path
  RESULT:
  The tool path is correct
  3) Edit the tool path and modify the angle value 97
  to 98 in 'Strategy/Machining' for Lift off angle
  4) Compute the toolpath
  5) Replay the tool path
  PROBLEM:
  The tool path is incorrect
  .

  MODIFICATION:
  Note that the lead-in angle is defined with respect
  to the normal to the cutting direction. Range of
  lead-in angle is from -90 degree to 135 degree for
  all the tools except for Grooving tool, where it
  ranges from 0 degree to 90 degree.
  .
  Note that the lift-off angle is defined with respect to
  the normal to the cutting direction. Range of lead-in
  angle is from -90 degree to 135 degree for all the
  tools except for Grooving tool, where it ranges
  from 0 degree to 90 degree.
  .
  For groove inserts, range of lead-in and lift-off has
  always been 0 to 90 degrees. This can be tested by
  using Groove inserts in a Grooving operation,
  where there is an explicit error message, in case
  these angles are set > 90.
  There are a number of ways to obtain the correct
  tool path.
  a) Use a Grooving operation with Groove inserts as
  mentioned above
  b) Any other operations with Groove inserts should
  also follow the above rule
  c) Use of Profile Finishing with other inserts
  .
