PURPOSE:To generate a plane figure, which is generated conventionally with plural blocks, with one block by expressing a continuous 4- or 5-component segment element with the command of one block using a specific preparatory word and a specific address. CONSTITUTION:For example, when a numerical control device receives a command with a preparatory word G105, a line of the fifth block which passes a point F(xf,yf) and makes an angle (a3) to the (y) axis is obtained, and the connecting line of a point N(xn,yn) and a contact E(xe,ye) of the fifth block on an arc which has the point N(xn,yn) as the center is set as a radius (r2). A line which passes a point A(xa,ya) and makes an angle (a2) to the (y) axis is obtained as the third block, and a line which passes the start point A of the line of the first block and makes an angle (a1) to the (y) axis is obtained as the fist block, and an arc which contacts with the first block and the third block and has a radius (r1) is obtained as the second block, and then, respective arcs of the second block and the fourth block are obtained as arcs in opposite directions, and one curve is formed as the whole. The block of this preparatory word is expressed by a formula. |
