Abstract

PURPOSE:To improve the ratio of an actual cutting time to a total cutting time for improving machining efficiency by digitizing air cut portions other than the copy mode out of copy sequences as a rapid feed instruction. CONSTITUTION:In surface one way copying, when copying reaches a limit LYP1 on the plus side of the Y axis, a stylus moves to a limit LZP3 on the plus side of the Z axis at a rapid speed and, in addition, to a limit LYN2 on the minus side of the axis. And then after moving to the approach limit LRA4 of the Z axis, it is brought into contact with a copying model 1 at a set up approaching speed and performs copying motion. And in an actual digitizing, presetting of the location of each limit in a controlling circuit allows the start and end of air cut portions A-C to be readily marked by watching the current location of each part of a machine. Machining efficiency can, thus, be improved.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a copying control method, and is applicable to copying machines, digitizers,
This is useful when digitizing with a three-dimensional measuring device, etc.

<Prior Art> Conventionally, as shown in FIG. 4, the air cut portion 2 of the copying sequence other than the copying mode in which the copying model 1 is copied has been digitized as a block of a cutting feed command (GOI).

<Problems to be solved by the invention> In the conventional technology, digitized position information is
Since the air cut portion 2 was output as a block of the cutting feed command (GOI), the machining process took an unnecessary amount of time, leading to a decrease in machining efficiency.

An object of the present invention is to provide a tracing control method that can improve machining efficiency using digitized data by combining the air cut portions, which were conventionally output as multiple blocks of cutting feed commands, into one block of rapid feed commands. do.

Means for Solving the Problems〉 The configuration of the present invention that achieves the above object is that in a scanning control method in which digitizing is performed using a copying machine, a digitizer, a three-dimensional measuring device, etc., operations other than the copying mode of the copying sequence According to the present invention, as shown in FIG. As shown in FIG. 3, when outputting digitized data, pay attention to the air cut start and end marks, and output the data between them as one block of fast forward command (Goo).

Example of implementation Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 shows an example in which the present invention is applied to surface scanning in one direction.

Since the same applies to other copying modes, FIG. 1 is taken as a representative example of the present invention.

As shown in the figure, when scanning a surface in one direction, when the scanning reaches the Y-axis positive side mitt LYP■, the stylus moves rapidly to the Z-axis positive side mitt LZP■, and then moves to the Y-axis negative side mitt LYN■. After the movement, it moves to the Z-axis abroach remisor l-L RA■, and then contacts the copying model 1 at the set approach speed to perform a copying operation. Therefore, the air cut portion 2 is A, I3 in FIG. This will be part C.

When actually digitizing, each limit LYP■, LZ
The positions of P■, LYN■, and LRA■ are set in advance in the copying controller and are known, so it is possible to easily mark the start and end of air cutting by monitoring the current position of the machine. .

Next, when outputting as digitized data, the digitized data from the block with the air cut start mark added earlier to the block with the air cut end mark is integrated, combined into one block, and a code GOO indicating a fast forward command is added and output. . That is, ABC in FIG. 1 are each combined into one block by the above processing, and F is output as conventional data without performing the above processing.

<Effects of the Invention> As specifically explained above in conjunction with the embodiments, the present invention has the following effects.

(1) In conventional digitizing machines, the air cut part unrelated to cutting is fed at the same cutting speed as the cutting part, so the actual cutting time accounts for a small proportion of the total cutting time, leading to a decrease in machining efficiency.However, the present invention Since the air cut portion is fed in rapid traverse, the ratio of actual cutting time to the total cutting time increases, significantly improving machining efficiency.

(2) Air Ka!・Collect the board number blocks for each part.
Since it is a block diagram, the amount of digitized data is small, and the storage capacity of the medium can be reduced.
