नीचे बताए गए Operation हम Cnc Machine पर कर सकते हैं तो चलिए जानते हैं कि वह कौन-से Operation हैं जिन्हें हम इस मशीन पर कर सकते हैं।
CNC Machine-Operation

1 Turning 
Turning Operation Cnc Machine Work Piece के बाहरी सतह पर कटाई करता है। Work  Piece को मशीन के  Center मे Jaw  पर Clamp किया जाता है। Turning Operation दो प्रकार के होते हैं।

(a) Straight Turning
Straight Turning Produce a Cylindrical piece of work on Which the diameteris uniform in Size throughout its entire length.

(b) Shoulder Turning
Shoulder Turning से मतलब यह होता है कि एक वर्क पीस पर दो या दो से अधिक व्यास कटता है। A Shoulder is formed ath tha point where the size Changes form one Diameter to Another. इसे Shoulder Turning कहते हैं।

(c) Taper Turning
जब कटिंग वर्क पीस के रोटेशन Axis Angle पर चलते हैं तो शंक्वाकार ( conical ) Surface बनातीं है। इसे taper Turning कहते हैं।

(d) Eccentric Turning
Fig Shows the Machining of the Eccentric with a hub ,D. The workpiece is Mounted on a mandrel. the Centres of the Eccentric are laid out on both ends of the mandrel can be held Eccentrically between live centre and Dead Centre in the table.then the Eccentric surface E and F are Machined .

(2) Chamfering
specified Angle on the end of a turned diameter . This is done by removing the sharp edge. Chamfering is done by setting the Compound slide at an angle and feeding the tool bit by hand to produce a specified chamfer. Chamfering removes burrs from the end of the workpiece and provides it a better appearance . A threaded job is generally chamfered so that the nut may be easily passed on it.

(3) Threading
यह operation workpiece के बाहरी बेलनाकार सतह पर चूड़ी (Threading) पड़ती है। हमारा वर्क पीस jaw और Center के बीच होता है। फिर एक टूल की मदद से वर्क पीस पर चूड़ी (Threading) डाली जाती है। Longitudinal feed is equal to the feed of the thread to be cut.

(4) Kunrling
Kunrling operation produces depression or indentation of various shape in to the workpiece by the use of revolving hardened steel wheels pressed against the workpiece . Since kunrling produce a roughened on a workpiece ,it provides an effective gripping surface on the workpiece to avoid slipping when work by taking in hand.


(5) Forming
Forming is the process of machining a convex, concave or of any irregular shape on the workpiece.  For turning a small length of formed surface a forming tool as shown in fig. is fed straight into the workpiece.  The forming tool has cutting edges conforming to the required shape. Forming is mainly a finishing operation.  For sufficiently large surfaces, a straight turning tool is used.  This requires both longitudinal and cross - feed simultaneously into the workpiece.  This process is tedious and requires much skill.  For turning a large number of wide surfaces a template having the desired shape is attached to the rear end of the lathe bed   when carriage travel longitudinal the tool will reproduce the contoured surface of the template as the guide block will trace the curved path.

(6) Facing
Facing operation, machines the ends of workpiece. It provides a surface which is square with the axis of the workpiece from which to start the job.  Facing can also decrease the length of the job.  Facing is done by feeding the cross - slide or compound (by hand) in or out.  In facing, the cutting tool moves from the center of the job towards its periphery and vice versa.

(7) Grooving
Undercutting is shown in fig. It is an operation of reducing the diameter of a workpiece over a vary narrow surface. In this operation, a tool of appropriate shape is fed into the revolving work up to the desired depth at right angle to the centre ling of the workpiece.

(8) Drilling
Drill operation is shown is fig it is an operation of making a hole in a workpiece with the help of the drill. In this operation, the workpiece is held in a Chuck and the drill is held in a tailstock. The drill is fed manually into the rotating workpiece, by rotating the tailstock head wheel.

(9) Reaming
Reaming operation is shown in fig. It is an operation of finishing the previously drilled hole. In this operation, a reamer is held in the tailstock and it is fed into the hole.

(10) Boaring
It is an operation of enlarging of a hole already made in a workpiece. In this operation a boring tool is held in the tool post and fed onto the work by hand and power.

(11) Undercutting
Undercutting is shown in fig. It is an operation of reducing the diameter of a workpiece over a vary narrow surface. In this operation, a tool of appropriate shape is fed into the revolving work up to the desired depth at right angle to the centre ling of the workpiece.
