Chapter 26, Problem 43QTP
It is known that, in grinding, heat checking occurs when grinding is done with a spindle speed of 5000 rpm, a wheel diameter of 8 in., and a depth of cut of 0.0015 in. for a feed rate of 50 ft/min. For this reason, the standard operating procedure is to keep the spindle speed at 3500 rpm. If a new, 10-in.-diameter wheel is used, what spindle speed can be used before heat checking occurs? What spindle speed should be used to keep the same grinding temperatures as those encountered with the existing operating conditions?

Students have asked these similar questions
In a surface grinding operation performed on a 6150 steel workpart (annealed,
approximately 200 BHN), the designation on the grinding wheel is C-24-D-5-V.
Wheel diameter =178 mm and its width= 25 mm. Rotational speed = 3000 rev/min.
Infeed = 0.05 mm per pass, crossfeed = 12.5 mm, and workpiece speed = 6 m/min.
This operation has been a source of trouble right from the beginning. The surface
finish is not as good as the 0.4 µm specified on the part print, and there are signs of
metallurgical damage on the surface. In addition, the wheel seems to become
clogged almost as soon as the operation begins. In short, nearly everything that can
go wrong with the job has gone wrong. (a) Determine the rate of metal removal
when the wheel is engaged in the work. (b) If the number of active grits per cm? =
30, determine the average chip length and the number of chips formed per time. (c)
What changes would you recommend in the grinding wheel to help solve the
problems encountered? Explain why you…
The specification of grinding when is given
2 Answer the following questions by circling True or False.
1. Open structures are used for precision forms and profile grinding.
2. In centre-less grinding operation, it is possible to grind cylindrical workpiece without actually fixing
the workpiece using centres or a chuck.
( )
3. Since all the machining parameters are built into the broach, very little skill is required from the
operator.
( )
4. The machined surface should be used as the clamping surface as it can improve the clamping
stability.
5. During the measurement, a comparator is able to give the deviation of the dimension from the set
dimension.
