CNC मशीन मे G74 Cycle Use करके Programme केसे बनाये

                दोस्तों CNC मशीन मे Part का Internal ऑपरेशन करने के लिये Drilling करना जरूरी हे.Drilling Operation Manually and Cycle use करके कर सकते हे.G74 Cycle Job के Facing करने के बाद use होती हे or Job की Clean Through Face होती हे तभी हम G74 Cycle Use कर सकते हे.Part को ड्रिलिंग करते समय Drill को Part की Length से 2 mm से 5 mm ज्यादा Drill करना होता हे क्युकी आप Part के Length के हिसाब से ड्रिल करोगे तो आप का ड्रिल पूरे Part को ड्रिल नहीं कर पायेगा इसी लिये आप को ड्रिलिंग करने के टाइम पे आप को ऐ चीज द्यान रखना हे की पूरा ड्रिलिंग करने के लिये 2 mm या 5 mm ज्यादा ड्रिल कर लेना ताकि आप का Part पूरी तरह से ड्रिल हो सके.तो दोस्तों आप को मे दो तिन Part Turning ओर ड्रिलिंग का Programme केसे बनाते हे. वो बताने जा रहा हु.तो इस आर्टिकल को पूरा पढ़े.

RPM SEARCH FORMULA

      RPM :      CS × 1000 / ∏ × D

इसमे आप को Ext.Turning,CenterDrill,Drilling आदि का RPM Search करना पड़ेगा. ऐ सब RPM Search करने के लिये उपर Formula दिया गया हे उसको उस करके आप RPM Search कर सकते हो.
