Abstract
A pulse generation means that generates a pulse each time an XY movable member moves linearly by a certain amount relative to a base is provided. A workpiece and a light and dark pattern member are provided on the base. A tool, a light and dark pattern scanning sensor that scans the light and dark pattern and outputs a scanning signal, and a cutting means that moves the tool with respect to the workpiece in a cutting depth direction, orthogonal to the linear motion direction, are provided on the XY movable member. While the XY movable member moves relative to the base, the tool is moved by the cutting means in accordance with a logical AND operation performed on the scanning signal from the light and dark pattern scanning sensor and the pulse from the pulse generation means to perform machining.
Claims10
A machining apparatus comprising:
- a linear driving means for linearly moving a first member in a first direction relative to a second member placed opposite to the first member;
- and
- a pulse generation means for generating a pulse each time the first member moves a certain amount relative to the second member,
- wherein an area for placing a workpiece is provided on the first or second member, and a light and dark patterned member having a light and dark pattern indicating machining information is placed on the first or second member,
- a light and dark pattern scanning sensor for scanning the light and dark pattern and outputting a scanning signal, a tool for machining the workpiece, a cutting means for making the tool cut into the workpiece in a direction orthogonal to the first direction, and a cutting means driving section for driving the cutting means are provided on the second or first member, and
- the cutting means driving section machines the workpiece by having the cutting means operate the tool according to output of a logical AND operation performed on the scanning signal from the light and dark pattern scanning sensor and pulses from the pulse generation means while the first member moves relative to the second member.
