CNC Machine मे Facing Operation का Simple Mathod से Programme केसे बनाये .

 

CNC मशीन मे SOLID MATERIAL & HOLE वाले MATERIAL का FACING केसे करे.

CNC मशीन मे SOLID MATERIAL का FACING करने के लिये पहेले CNC lathe मशीन के प्रोग्रामिंग दोरांत जिस block मे पहेले G01 Code आता हे उस block मे एकबार Feed Value देना पडता हे.

CNC मशीन के Programming टाइम पे जो Feed Value नहीं डाली हो तो Display Screen पे No Feed Rate Commanded Alarm Massage देखने को मिलेगा.

CNC मशीन मे Facing Operation टाइम पे Solid Material हो तो Tool को Center से 2 mm –minus मे निचे लेना होता हे.

CNC मशीन मे MATERIAL का RPM निकाल ने के लिये निचे दिया गया Formula Use करना पडता हे.

RPM SEARCH FORMULA

RPM : Revolustion Per Minute

CS : Cutting Speed

∏  : 3.14

RPM : CS × 1000 / ∏ × D

      200 × 1000 / 3.14 × 30 = 2900

उस के लिये Cutting Feed Material के हीसाब से रखना पडता हे.

SINGLE TOOL FACING OPERATION  PROGRAMME केसे SIMPLE तरीके से बनाये. (HOLE MATERIAL)           

CNC मशीन मे Hole वाले Part का Facing Operation करने के लिये Facing Operation टाइम पे Hole जेसा Material हो तब जितने MM का Hole हो उससे 2 MM कम Diameter तक Tool द्वारा Facing करवाना चाहिये.
