• Width and depth of the slot define the milling tool. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Side and face milling cutters offer the most efficient procedure for the milling of big volumes of long and deep of slot, especially when horizontal milling machines are used.
• The workpiece is fixed firmly on a milling machine and fixing the end milling cutter on an arbor, by adjusting the depth of cut, the work is fed against the cutter to cut the groove on the work surface. Gang milling Operation.
• By taking a depth of cut of 1D per pass, you may go as deep as the tool shank will allow. Good chip flushing with either air or liquid coolant is essential so you are not re-cutting chips as they fill the pocket. It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
• Depth of cut (Ap1).200' feed (vf) 19.5 ipm. 4140, 220 HB “K” factor 1.56. MRR = Ap1 x ae x vf. Whether face milling, periphery milling, slot milling,.

A slot drill is just a 2-flute end mill used for cutting a slot, as per the name, more clearance for the chips to come out of the back without clogging then, there'll be one flute cuts over centre so it can be used to plunge cut small distances too, to start slots in the middle of material.

Summary

Q. Write a CNC Part Program for the figure shown

Slot Milling Depth Of Cut

For side milling, take speed 1200 rpm & feed 100 mm/min
For drilling holes, take speed 1200rpm & feed 80mm/min
For slot milling, take speed 1200rpm & feed 120mm/min
Take hole diameter as 15mm
Use absolute coordinate system.

Solution:

Sequence of operation:
1 Set ref point, cordinate system, tool, give feed & speed value
2 Set cutter for radius compensation left offset
3 set tool at A, start spindle & give down feed (-Z direction)
4 proceed further cutting of side milling and stop spindle at A
5 Move tool at ref point & set the tool for slot cutting
6 Move tool to P, start the spindle & give down feed
7 Proceed further cutting of slot milling and stop spindle at S
8 Move tool at ref point & set the tool for drilling
9 Move tool to P, start the spindle & give full depth cut
10 Move tool up & stop the spindle.
11 Bring back tool at refrence point.
12 End of the program
