A new digital measurement method for accurate curve
grinding process

1 Introduction
Grinding is commonly used as the final machining process
to ensure product quality because of its high precision [1].
In recent years, high efficiency and high-performance CNC
grinding machines have appeared and grinding apparatus
manufacturing technology has improved. The new grinding
machine has higher precision, but there is a lack of effective
online detection or monitoring methods for the grinding
process. Online detection plays an important role in the
abrasive machining process [2].
In precision cutting tools and dies manufacturing, the
final machining process is curve grinding. In this process,
the grinding wheel wear will create machining errors. It is
well known that the grinding wheel should be compensated
when the wheel is worn out. The online measurement of
grinding wheel wear and work piece is required.
At present, there are several methods for grinding wheel
wear monitoring and inspection such as acoustic emission
testing, hydrodynamic measurement in wet grinding,
optical projection reading method, etc. [3–7]. The acoustic
emission method is a dynamic nondestructive examination
technology. An acoustic emission sensor is used in contact
measurement to detect acoustic emission signals from the
touch of the grinding wheel on a work piece. The wearing
degree of the grinding wheel can be estimated by analyzing
acoustic emission signals [4]. Acoustic emission signals are
mainly composed of elastic contact between grinding wheel
and work piece, grinding wheel binder breakage, abrasive
particle breakage and work piece surface cracks, etc. It is
difficult to identify the different emitters for the acoustic
emission testing method [5]. Thus the grinding wheel status
cannot be estimated properly.
In wet grinding, a pressure sensor was set beside the
grinding wheel with a small gap. Hydrodynamic pressure,which corresponds to the gap length and the topography,
can be measured when grinding fluid was dragged into the
gap by the rotation [6]. Its principle is shown in Fig. 1.
For traditional optical curve grinding machines, the
grinding status estimation depended on optical projection
reading. It is a non-contact, full field of vision measurement
method. Its measurement principle is shown in Fig.
