ABSTRACT:
There is disclosed a scale control device for use in a profiling machine tool, which comprises: relative displacement detecting means detecting a relative displacement and a displacing direction of a tool head with respect to a work, thereby producing output signals including data of relative displacement and the direction of the displacement; feedback signal producing means receiving the output signals from the relative displacement detecting means and converting the output signals into feedback signals which have been frequency-divided at a pre-set desired ratio; and model drive mechanisms displacing a model relative to the work in a direction the same as or reverse to the moving direction of the tool head with respect to the work, in response to the feedback signals and in proportion to a relative displacement between the tool head and the work.
