Scarfing is a common repair technique used on thin walled composites. This work explores the parameters used in scarfing. The STARC robot performed all scarfs. This robot was developed by a company named PushCorp and is a Stewart platform. The parameters are simplified to the scarf angle, pitch, feed rate, and spindle rate. The different roughness patterns are analyzed as these parameters are varied. With the set range, the parameters showed the following trends: (1) Higher scarf angle yielded higher roughness; (2) Higher pitch yielded lower roughness; (3) Higher spindle rate yielded higher roughness; (4) Higher feed rate yielded higher roughness.; Several charts and relationships are developed using Minitab, and an ANOVA table is generated to ensure statistical accuracy. Recommendations for future experiments as well as changes in the STARC robot are included. |
