Explain Feed - Cutting Parameters
1. In cylindrical grinding feed is the longitude movement of the work piece per revolution.
f=Feed in mm per work piece revolution.
=K1B
Where B=Face width of wheel in mm.
K1=Constant.
=0.4 to 0.6 for finish grinding
= 0.6 to 0.9 for rough grinding
2. Work or table traverse in meter/minute
=f × N/1000
Where N=Work piece speed in R.P.M.
Ratio of belt tension: For Open belt drive: Angle of contact (θ) for larger pulley = ∏ + 2α Angle of contact (θ) for smaller pulley = ∏ - 2α For cross belt drive:
