The workpiece must always be secured to the milling table in a machine vice, chuck or
with another suitable clamping tool, such as a workholding device (clamping claws).
4.14.1 Calculation of the Cutting Forces or Necessary Holding Force when Milling
The cutting force Fc arising between the tool and workpiece when milling can be calculated
using the Viktor/Kienzle formula:
In this formula, there are 5 factors which are completely unknown without more detailed
knowledge. However, these factors can be determined using tables.
The specific cutting force
kc1.1
and the chip thickness exponent
mc
are dependent on the
material used. Both parameters are present in tabular reference books and must be
investigated for the corresponding material.
Furthermore, for the calculation of the cutting force
Fc
according to the Kienzle equation, the
chip width
b
, the chip thickness
h
, and the correction factor
K
are needed.
We recommend using a machining technology paperback
ISBN 978-3-8085-1473-3 (example, only in German language available). In these reference
table books you will find all the necessary and additional information. These machining
technology reference table books should bridge the gap between the predominantly theory-
oriented textbooks and reference & reference table books mostly written with the few theoretical
principles in practice.
