3 Terms and definitions
3.1 General
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following
apply.
3.2 Definitions
3.2.1
routing machine
C-frame type machine for the moulding of workpieces by means of:
8
---------------------- Page: 9 ----------------------
EN 848-2:2007 (E)
-1
a) one tool spindle located above the table and running at speeds between 6 000 min and generally
-1
24 000 min . The work head is tiltable or not and may be movable only along the direction of the axis of
the tool during machining;
b) a table to support the workpiece or jig. The table is tiltable or not and/or movable in X, Y and Z directions
and/or adjustable round the C axis;
c) the tool spindle/work head is either manually or power driven moved vertically during machining or moved
by means of hydraulic or pneumatic devices. The workpiece is normally fed to the machine in a direction
opposite to the direction of the tool spindle either manually or by means of an integrated feed system
3.2.2
straight work
shaping of a workpiece with one face in contact with the table and a second with the fence and where the
work starts at one end of the workpiece and continues through to the other end (see Figure 1)
Key
1 machined edge
Figure 1 — Example of straight work
3.2.3
stopped straight work
machining of only a part of the workpiece length (see Figure 2)

Key
1 machined edge
Figure 2 — Example of stopped straight work
3.2.4
shaped work
machining of a curve at the edge or on the surface of a workpiece
NOTE 1 One of the techniques is attaching the workpiece to a jig. On the underside of the jig is a template which is in
contact with a reference pin located in the centre of the table directly below the cutter. The jig is moved past the pin, but in
contact with it, thereby reproducing the shape of the template on the workpiece (see Figures 3 and 4).
