HE09749: Prismatic Machining: Profile Contouring; Machining tolerance is not respected

APAR status

• Closed as program error.

Error description

• Description:
  Operation Profile Contouring, Tool path style Helix is computed
  with Machining tolerance 0.02mm. The real tolerance is 0.44mm.
  Scenario:
  1. File -> Open-> Process1.CATProcess
  2. Check the Machine Editor, only 3D linear interpolation is sel
  ected.
  3. Check the Profile Contouring.1 operation
  Tool path style: Helix
  Machining tolerance: 0.02mm
  Compensation output: 2D radial profile
  4. Replay the tool path.
  Actual result:
  APT output is white polyline, because of Compensation output: 2D
   radial profile. The yellow points are points from APT output. T
  he machining tolerance 0.02mm is not respected on the helix port
  ion of tool path. The real tolerance is 0.44mm. This is the erro
  r.
  Expected result:
  Compare point distribution on circular tool path and point distr
  ibution on helix tool path. The point distribution should be the
   same.

Problem summary

• Description:
  Operation Profile Contouring, Tool path style Helix is
  computed with Machining tolerance 0.02mm. The real tolerance
  is 0.44mm.
  Scenario:
  1. File -> Open-> Process1.CATProcess
  2. Check the Machine Editor, only 3D linear interpolation is
  selected.
  3. Check the Profile Contouring.1 operation
  Tool path style: Helix
  Machining tolerance: 0.02mm
  Compensation output: 2D radial profile
  4. Replay the tool path.
  Actual result:
  APT output is white polyline, because of Compensation output:
  2D radial profile. The yellow points are points from APT
  output. The machining tolerance 0.02mm is not respected on
  the helix portion of tool path. The real tolerance is 0.44mm.
  This is the error.
  Expected result:
  Compare point distribution on circular tool path and point
  distribution on helix tool path. The point distribution
  should be the same.
  

Problem conclusion

• THIS PROBLEM HAS BEEN FIXED ON V5R20 SP7, V5R21 SP2 AND V5R22
  GA
  Additional Closure Information:
  Technical explanation of the defect:
  Distribution points on profile data do not respect the
  machining tolerance.
  Technical explanation of the correction:
  Tolerance is only taken into account for the tool tip
  machining traject but not for the profile data.
