1.1	1	(% style="color:#a0be2d" %)//G81 (X- Y- Z-) or (U- V- W-) R- L-//
	2
4.1	3	The (% style="color:#a0be2d" %)//G81//(%%) cycle is designed for drilling.
1.1	4
4.1	5	The cycle includes the following actions:
1.1	6
4.1	7	1. Preliminary movement described in the section "[[Canned Cycles>>doc:Руководство пользователя.Описание G-кодов.Список G-кодов, поддерживаемых системой.G80-G89\: Постоянные циклы.WebHome]]".
	8	1. Move the Z axis with the current feedrate to Z position.
	9	1. The Z axis moves quickly to the return height along Z.
1.1	10
4.1	11	====== Example 1 ======
1.1	12
4.1	13	Suppose the current position (X1, Y2, Z3) and the following line of G-code is executed:
1.1	14
	15	(% style="color:#a0be2d" %)//G90 G98 G81 X4 Y5 Z1.5 R2.8//
	16
4.1	17	In the example, when the command is executed, the absolute positioning mode ((% style="color:#a0be2d" %)//G90//(%%)) and the mode of returning to the initial height in Z ((% style="color:#a0be2d" %)//G98//(%%)) are valid.
1.1	18
4.1	19	The following movements will take place:
1.1	20
4.1	21	1. Quick movement in the XY plane to the point (X4, Y5).
	22	1. Fast movement along the Z axis to a point (Z2.8).
	23	1. Moving along the Z axis at a given feedrate in (Z1.5).
	24	1. Fast movement along the Z axis in (Z3).
1.1	25
4.1	26	[[Command (% style="color:#a0be2d" %)//G81//(%%). Example 1>>image:image2019-6-4_14-4-45.png\|\|alt="Команда (% style=" data-xwiki-image-style-alignment="center"]]
1.1	27
4.1	28	====== Example 2 ======
1.1	29
4.1	30	Suppose the current position (X1, Y2, Z3) and the following line of G-code is executed:
1.1	31
	32	(% style="color:#a0be2d" %)//G91 G98 G81 X4 Y5 Z-0.6 R1.8 L3//
	33
4.1	34	In the example, when executing the command, the incremental positioning mode ((% style="color:#a0be2d" %)//G91//(%%)) and the mode of returning to the initial height in Z ((% style="color:#a0be2d" %)//G98//(%%)) are effective. The machine performs a drilling cycle three times. The initial position in X is 5 (= 1 + 4), the initial position in Y is 7 (= 2 + 5), the return height in Z is 4.8 (= 1.8 + 3), the target position in Z is 4.2 (= 4.8-0.6 ) The initial position in Z is 3.
1.1	35
4.1	36	During the preliminary movement, a quick movement along the Z axis to the position (X1, Y2, Z4.8) is made, since the initial height in Z is less than the return height.
1.1	37
4.1	38	The first iteration of the loop consists of 3 movements:
1.1	39
4.1	40	1. Fast movement in the XY plane in (X5, Y7).
	41	1. Moving along the Z axis at a given feedrate in (Z4.2).
	42	1. Fast movement along the Z axis in (X5, Y7, Z4.8).
1.1	43
4.1	44	The second iteration of the loop consists of 3 movements:
1.1	45
4.1	46	1. Fast movement in the XY plane in (X9, Y12, Z4.8).
	47	1. Movement along the Z axis with a given feedrate in (X9, Y12, Z4.2).
	48	1. Fast movement along the Z axis in (X9, Y12, Z4.8).
1.1	49
4.1	50	The third iteration of the cycle consists of 3 movements:
1.1	51
4.1	52	1. Fast movement in the XY plane in (X13, Y17, Z4.8).
	53	1. Movement along the Z axis with a given feedrate in (X13, Y17, Z4.2).
	54	1. Fast movement along the Z axis in (X13, Y17, Z4.8).
1.1	55
4.1	56	[[Command (% style="color:#a0be2d" %)//G81//(%%). Example 2>>image:image2019-6-4_14-6-45.png\|\|alt="Команда G81. Пример 2" data-xwiki-image-style-alignment="center"]]
1.1	57
4.1	58	====== Example 3 ======
1.1	59
4.1	60	Suppose that the current position (X0, Y0, Z0) instead of (X1, Y2, Z3), and a line of G-code is executed:
1.1	61
	62	(% style="color:#a0be2d" %)//G90 G98 G81 X4 Y5 Z1.5 R2.8//
	63
4.1	64	Since the initial height in Z is less than the value of the parameter R, during the preliminary movement, the initial movement in Z will be performed.
