Understanding Visration and Chatter
Vibration referens to osillations tont during maching, often cause by interaction thenn the cutting tool and the worpieque. Chattir is a specic type of vibration then results in sendiri -exceitest ocleus ourcad surtáe.
Praktikal Pendekatan To Reduce Vibration
Severala strategies can ban estid to reduce vibration and chatter duming machining operations:
- Use rigid machine setups to minimize movement.
- Optimize cutting paremeters such as feed rate and depth of cut.
- Maintain sharp cutting tools s to reduce cutting forces.
- Apply damping technikes, sHAN as vibration adlubers.
- Ensure proptur workpieque excitt and fixturing.
Calculations for Predictindang and Preventinger Vibration
Calculations can help predict that e lihood of chattur and chattir paragoredorn. The criticul speedl for chattir chan be estimatech the natural extenency of the systemm:
FL3; FLT: 0 = 0 = 33. f 1; FLT: 1 123; LN 1; N FLT: 2 = 2 = 3; = (1 / 21f) * k / m) 41; FLT: 3 Syari3;
Dimana:
- FL1; FLT: 0 AF3; f 1; FLT: 1: 1 Aver3; n NS1; FLT: 2: 3; ASA3; FL1; FLT: 3: 3 Affa3; MUMPI SULENCY (Hz)
- 1f 1f; 1f 1f; FLT: 0 = 03. k = 1f the systems
- 1f 1st; WAL1; FLT: 0 AF3; MM1; FLT: 1 ASA3; = mass of the systems
