Automatic recognition of geometrical dimensioning and tolerances from a STEP file
The geometrical dimensioning and tolerances for each feature plays a key role in the manufacturing of a product. Based on this, parts datum, fixtures, type of tool and no. of passes is decided. The neutral file acts as a connection between the design and manufacturing phase. In the present work, a p...

| description | The geometrical dimensioning and tolerances for each feature plays a key role in the manufacturing of a product. Based on this, parts datum, fixtures, type of tool and no. of passes is decided. The neutral file acts as a connection between the design and manufacturing phase. In the present work, a program is developed for the extraction of various entities from the STEP which is a neutral file. This extracted data is taken as input and using different rules machining features and corresponding tolerances are recognized. Various case studies are verified using the developed program. In the present paper, one of the case study results is presented. This recognized data further can be used to generate an NC code. In turn, this is given as input to the CNC machine for manufacturing of the part. |
